Abstract

System and method for incrementally notifying a remote client of updates in a cloud-enabled platform for each remote client associated with a collaborator are disclosed. In one aspect, embodiments of the present disclosure include a method, which may be implemented on a system, for detecting an action in the cloud-enabled platform and effectuating a data change as a result of the action in a first database, creating an action log entry from the action, identifying the collaborator of the user's in the cloud-enabled platform, whose remote client is to be synchronized with the data change as an update, and/or writing the action represented by the action log entry to a second database into a queue to by read by the remote client of the collaborator.

Description

BACKGROUND

With the increase of electronic and digital content being used in enterprise settings or other organizations as the preferred mechanism for project, task, and work flow management, as has the need for streamlined collaboration and sharing of digital content and documents. In such an environment, multiple users are sharing, accessing and otherwise performing actions or tasks on content and files in a shared work space, where any number of users may have access to a given file or may want to or need to perform an action on the file at any given time.

The cloud-based nature of such an environment enables users/collaborators to access, view, edit content anytime, from any device, or using any number of and/or types of clients, simultaneously while other collaborators in the same group, enterprise, or other types of formal/informal organizations may also be accessing, viewing, or editing the same file or content or content in the same work group. The different types of clients and number devices which can be used to access a single account or work item or work group the cloud content and environment introduces the problem of maintaining consistency and correct ordering in how changes are reflected at the clients used by users to access the cloud-based platform and content.

Embodiments of the present disclosure include systems and methods for resource effective incremental updating of a remote client with events which occurred via a cloud-enabled platform.

FIG. 1 illustrates an example diagram of a system having a host server 100 of a cloud-enabled platform able to incrementally update remote clients (clients 110, 120, 130, 140, 160) at devices 102 with events that occurred via the platform hosted by server 100.

The client devices 102 can be any system and/or device, and/or any combination of devices/systems that is able to establish a connection, including wired, wireless, cellular connections with another device, a server and/or other systems such as host server 100 and/or notification server 150. Client devices 102 will typically include a display and/or other output functionalities to present information and data exchanged between among the devices 102 and/or the host server 100 and/or notification server 150.

For example, the client devices 102 can include mobile, hand held or portable devices or non-portable devices and can be any of, but not limited to, a server desktop, a desktop computer, a computer cluster, or portable devices including, a notebook, a laptop computer, a handheld computer, a palmtop computer, a mobile phone, a cell phone, a smart phone, a PDA, a Blackberry device, a Treo, a handheld tablet (e.g. an iPad, a Galaxy, Xoom Tablet, etc.), a tablet PC, a thin-client, a hand held console, a hand held gaming device or console, an iPhone, and/or any other portable, mobile, hand held devices, etc. running on any platform or any operating system (e.g., Mac-based OS (OS X, iOS, etc.), Windows-based OS (Windows Mobile, Windows 7, etc.), Android, Blackberry OS, Embedded Linux platforms, Palm OS, Symbian platform. In one embodiment, the client devices 102, host server 100, and notification server 150 are coupled via a network 106 and/or a network 108. In some embodiments, the devices 102 and host server 100 may be directly connected to one another.

The input mechanism on client devices 102 can include touch screen keypad (including single touch, multi-touch, gesture sensing in 2D or 3D, etc.), a physical keypad, a mouse, a pointer, a track pad, motion detector (e.g., including 1-axis, 2-axis, 3-axis accelerometer, etc.), a light sensor, capacitance sensor, resistance sensor, temperature sensor, proximity sensor, a piezoelectric device, device orientation detector (e.g., electronic compass, tilt sensor, rotation sensor, gyroscope, accelerometer), or a combination of the above.

Signals received or detected indicating user activity at client devices 102 through one or more of the above input mechanism, or others, can be used in the disclosed technology by various users or collaborators (e.g., collaborators 108) for accessing, through network 106, a web-based collaboration environment or online collaboration platform (e.g., hosted by the host server 100), any remote environment, or other types of services including any type of cloud-based service or storage environment.

The collaboration platform or environment hosts workspaces with work items that one or more users can access (e.g., view, edit, update, revise, comment, download, preview, tag, or otherwise manipulate, etc.). A work item can generally include any type of digital or electronic content that can be viewed or accessed via an electronic device (e.g., device 102). The digital content can include .pdf files, .doc, slides (e.g., Powerpoint slides), images, audio files, multimedia content, web pages, blogs, etc. A workspace can generally refer to any grouping of a set of digital content in the collaboration platform. The grouping can be created, identified, or specified by a user or through other means. This user may be a creator user or administrative user, for example.

In general, a workspace can be associated with a set of users or collaborators (e.g., collaborators 108) which have access to the content included therein. The levels of access (e.g., based on permissions or rules) of each user or collaborator to access the content in a given workspace may be the same or may vary among the users. Each user may have their own set of access rights to every piece of content in the workspace, or each user may be different access rights to different pieces of content. Access rights may be specified by a user associated with a work space and/or a user who created/uploaded a particular piece of content to the workspace, or any other designated user or collaborator.

In general, the collaboration platform allows multiple users or collaborators to access or collaborate efforts on work items such each user can see, remotely, edits, revisions, comments, or annotations being made to specific work items through their own user devices. For example, a user can upload a document to a work space for other users to access (e.g., for viewing, editing, commenting, signing-off, or otherwise manipulating). The user can login to the online platform and upload the document (or any other type of work item) to an existing work space or to a new work space. The document can be shared with existing users or collaborators in a work space.

A diagrammatic illustration of the cloud-based environment (e.g., collaboration environment) and the relationships between workspaces and users/collaborators are illustrated with further reference to the example of FIG. 2. A diagrammatic illustration of a workspace having multiple work items with which collaborators can access through multiple devices is illustrated with further reference to the example of FIG. 3.

Embodiments of the present disclosure relate to efficient updating of remote clients (110-170) on user devices 102 based on updates, changes that occur in the cloud environment at the host server 100 from user edits, updates, comments, etc. Since multiple users collaborate in the cloud-based environment hosted by server 100, user devices 102 need to be appropriately updated such that the most current versions of data/content are synchronized with the relevant user devices and that notification of events are sent to the relevant devices/users in a timely and orderly fashion. Any given user can utilize any number of clients and any number of types of clients (e.g., sync client, real time web client, mobile sync client, mobile application, email client, server sync client, etc.) at any given time. Thus, the host server 100 components further shown and described in FIGS. 4A-4B, FIGS. 5A-5D, and FIG. 6 facilitate the ordered syncing or updating of the remote clients which a given user/collaborator may use to access the cloud platform via any number of user devices 102.

In one embodiment, client devices 102 communicate with the host server 100 and/or notification server 150 over network 106. In general, network 106, over which the client devices 102, the host server 100, and/or notification server 150 communicate, may be a cellular network, a telephonic network, an open network, such as the Internet, or a private network, such as an intranet and/or the extranet, or any combination thereof. For example, the Internet can provide file transfer, remote log in, email, news, RSS, cloud-based services, instant messaging, visual voicemail, push mail, VoIP, and other services through any known or convenient protocol, such as, but is not limited to the TCP/IP protocol, Open System Interconnections (OSI), FTP, UPnP, iSCSI, NSF, ISDN, PDH, RS-232, SDH, SONET, etc.

The network 106 can be any collection of distinct networks operating wholly or partially in conjunction to provide connectivity to the client devices 102 and the host server 100 and may appear as one or more networks to the serviced systems and devices. In one embodiment, communications to and from the client devices 102 can be achieved by, an open network, such as the Internet, or a private network, such as an intranet and/or the extranet. In one embodiment, communications can be achieved by a secure communications protocol, such as secure sockets layer (SSL), or transport layer security (TLS).

In addition, communications can be achieved via one or more networks, such as, but are not limited to, one or more of WiMax, a Local Area Network (LAN), Wireless Local Area Network (WLAN), a Personal area network (PAN), a Campus area network (CAN), a Metropolitan area network (MAN), a Wide area network (WAN), private WAN, a Wireless wide area network (WWAN), enabled with technologies such as, by way of example, Global System for Mobile Communications (GSM), Personal Communications Service (PCS), Digital Advanced Mobile Phone Service (D-Amps), Bluetooth, Wi-Fi, Fixed Wireless Data, 2G, 2.5G, 3G, 4G, IMT-Advanced, pre-4G, 3G LTE, 3GPP LTE, LTE Advanced, mobile WiMax, WiMax 2, WirelessMAN-Advanced networks, enhanced data rates for GSM evolution (EDGE), General packet radio service (GPRS), enhanced GPRS, iBurst, UMTS, HSPDA, HSUPA, HSPA, UMTS-TDD, 1xRTT, EV-DO, messaging protocols such as, TCP/IP, SMS, MMS, extensible messaging and presence protocol (XMPP), real time messaging protocol (RTMP), instant messaging and presence protocol (IMPP), instant messaging, USSD, IRC, or any other wireless data networks or messaging protocols.

FIG. 2 depicts an example diagram of a web-based or online collaboration environment hosted by a cloud-based platform deployed or accessed by an enterprise or other organizational setting 250 for organizing work items 215, 235, 255 and workspaces 205, 225, 245.

The web-based platform for collaborating on projects or jointly working on documents can be used by individual users and shared among collaborators. In addition, the collaboration platform can be deployed in an organized setting including but not limited to, a company (e.g., an enterprise setting), a department in a company, an academic institution, a department in an academic institution, a class or course setting, or any other types of organizations or organized setting.

When deployed in a organizational setting, multiple workspaces (e.g., workspace A, B C) can be created to support different projects or a variety of work flows. Each workspace can have its own associate work items. For example, work space A 205 may be associated with work items 215, work space B 225 can be associated with work items 235, and work space N can be associated with work items 255. The work items 215, 235, and 255 may be unique to each work space but need not be. For example, a particular word document can be associated with only one work space (e.g., work space A 205) or it may be associated with multiple work spaces (e.g., Work space A 205 and work space B 225, etc.).

In general, each work space has a set of users or collaborators associated with it. For example, work space A 205 is associated with multiple users or collaborators 206. In some instances, work spaces deployed in an enterprise may be department specific. For example, work space B may be associated with department 210 and some users shown as example user A 208 and workspace N 245 can be associated with departments 212 and 216 and users shown as example user B 214.

Each user associated with a work space can generally access the work items associated with the work space. The level of access will depend on permissions associated with the specific work space, and/or with a specific work item. Permissions can be set for the work space or set individually on a per work item basis. For example, the creator of a work space (e.g., one of user A 208 who creates work space B) can set a permission setting applicable to all work items 235 for other associated users and/or users associated with the affiliate department 210, for example. Creator user A 208 may also set different permission settings for each work item, which may be the same for different users, or varying for different users.

In each work space A, B . . . N, when an action is performed on a work item by a given user or any other activity is detected in the work space, other users in the same work space may be notified (e.g., in real time or in near real time, or not in real time). Activities which trigger real time notifications can include, by way of example but not limitation, adding, deleting, or modifying collaborators in the work space, uploading, downloading, adding, deleting a work item in the work space, creating a discussion topic in the work space.

Specifically, items or content downloaded or edited in accordance with the techniques described in the present disclosure can be cause notifications to be generated. Such notifications can be sent to relevant users to notify them of actions surrounding a download, an edit, a change, a modification, a new file, a conflicting version, an upload of an edited or modified file.

In one embodiment, in a user interface to the web-based collaboration platform where notifications are presented, users can, via the same interface, create action items (e.g., tasks) and delegate the action items to other users including collaborators pertaining to a work item 215, for example. The collaborators 206 may be in the same workspace A 205 or the user may include a newly invited collaborator. Similarly, in the same user interface where discussion topics can be created in a work space (e.g., work space A, B or N, etc.), actionable events on work items can be created and/or delegated/assigned to other users such as collaborators of a given work space 206 or other users. Through the same user interface, task status and updates from multiple users or collaborators can be indicated and reflected. In some instances, the users can perform the tasks (e.g., review or approve or reject, etc.) via the same user interface.

FIG. 3 depicts an example diagram of a workspace 302 in a cloud-based platform such as an online, web-based or desktop collaboration environment accessible by multiple collaborators 322 through various devices via a web interface, mobile client, or desktop client.

Each of users 316, 318, and 320 can individually use multiple different devices to access and/or manipulate work items 324 in the work space 302 with which they are associated with. For example users 316, 318, 320 can be collaborators on a project to which work items 324 are relevant. Since the work items 324 are hosted by the collaboration environment (e.g., a cloud-based environment), each user can access the work items 324 anytime, and from any physical location using any device (e.g., including devices they own or any shared/public/loaner device).

Work items to be edited or viewed can be accessed from the workspace 302 in accordance with the platform and/or application independent mechanisms disclosed herein. Users can also be notified of access, edit, modification, and/or upload related-actions performed on work items 324 by other users or any other types of activities detected in the work space 302. For example, if user 316 modifies a document, one or both of the other collaborators 318 and 320 can be notified of the modification in real time, or near real-time, or not in real time. The notifications can be sent through any of all of the devices associated with a given user, in various formats including, one or more of, email, SMS, or via a pop-up window in a user interface in which the user uses to access the collaboration platform. In the event of multiple notifications, each notification can be depicted preferentially (e.g., ordering in the user interface) based on user preferences and/or relevance to the user (e.g., implicit or explicit).

For example, a notification of a download, access, read, write, edit, or uploaded related activities can be presented in a feed stream among other notifications through a user interface on the user device according to relevancy to the user determined based on current or recent activity of the user in the web-based collaboration environment.

In one embodiment, the notification feed stream further enables users to create or generate actionable events (e.g., as task) which are or can be performed by other users 316 or collaborators 322 (e.g., including admin users or other users not in the same work space), either in the same work space 302 or in some other work space. The actionable events such as tasks can also be assigned or delegated to other users via the same user interface.

For example, a given notification regarding a work item 324 can be associated with user interface features allowing a user 316 to assign a task related to the work item 324 (e.g., to another user 316, admin user 318, creator user 320 or another user). In one embodiment, a commenting user interface or a comment action associated with a notification can be used in conjunction with user interface features to enable task assignment, delegation, and/or management of the relevant work item or work items in the relevant work spaces, in the same user interface.

FIG. 4A depicts an example system block diagram showing the interaction between server-side components for incrementally updating a remote client with events or actions that occurred via a cloud-based platform.

The server-side includes front end components 402A-N, a database 410, a dispatcher 430, one or more processors 440A-N, and a second database (e.g., Hbase 460). The front end components 402A-N can interface with client devices/end user devices to detect/identify transactions or events. The data or file change that occur as a result of the event is effectuated in the database 410 of the cloud-enabled platform (e.g., the relevant changes are made in the file table 411 of the database).

Depending on the type of action or event, an action log entry can be created and stored in the action log 416. In general, the front end 402 determines whether an action log entry is created from a given action or transaction. In general, an action log entry can be created for an action or event if certain durability requirements are to be met. The dispatcher 430 reads the action log entries from the action log 416 and sends them to the processors 440A-N where the fan-out, or collaborators to be notified of the event or to receive the file/data change as a result of the event is determined. Based on the computed fan-out or identified collaborators, the processors 440A-N writes the events/transactions to the relevant queues in the second database 460, from which remote clients can read.

FIG. 4B depicts an example block diagram showing the interaction of remote clients 470A-N and 480A-N with a distributed database cluster 460 for incremental updates of events/actions which occurred at a cloud-based environment. The remote clients can include, for example real time clients 470A-N (e.g., real-time web clients launched via a web browser, mobile application), and synchronization clients 480A-N (e.g., desktop sync, mobile sync, server sync, etc.) that users or collaborators use to interface/access the cloud-based platform including but not limited to a collaboration environment. Other types of clients may also read from the database cluster 460.

The queues in the database 460 (e.g., the distributed database cluster) are usually client type specific. For example, each queue is for a given client type for one given user. So, a user ‘A’ may have a sync client queue that all of the sync clients that user “A” uses reads from since user “A” may have multiple devices on which sync clients are installed. In general, the queues for clients in the database 460 are read only queues such that multiple clients can read from the same queue without making modifications. In this manner, if a user utilizes multiple sync clients, each client can still receive and detect the respective updates such that multiple devices can be synchronized. The remote clients also typically individually track the location in the queue from which they last read such that only the most recent events are updated at the client, and that the events read from a queue is specific to a given client, dependent on what has previously been synchronized or read.

In one embodiment, sync clients 480 connect to both real-time 470 and API front end 490 machines. The real time machines 470 can notify a sync client 480 when there has been an update in a user's account. The sync client 480 can then connect to API front end machine 490 to obtain the actual change/content. Alternatively, in some instances, the sync clients 480 can also obtain the changes/content/updates from the real time machines 470 simultaneous with the notification, or after being notified.

FIG. 5A depicts an example system block diagram showing action log entries 516 recorded from actions/interactions on or with files/content 511 stored in a database 510 of a cloud-based environment.

The front ends 502A-N detect, identify, or receive the various actions or events on data or content performed by users or collaborators in a cloud-based environment. For example, events/actions can include by way of example but not limitation, file renames, file uploads/downloads, file edits, comments, etc. Based on the type of event, the front end 502 determines whether the action/event is to be created into a log entry to be stored in the action log 516. In creating a log entry, each action/event is recorded as a transaction with the file system change for asynchronous processing. In recording the transaction, the relevant file/folder row in the file 511 of the database 510 is inserted, updated, deleted, or otherwise modified according to the action. In one embodiment, the row is inserted in to the action log table 516 simultaneously with the write to the file 511 and also with the performance of action itself. Note that each entry includes an owner ID 514 in the file 511 and in the action log 516 to represent the owner of the item upon which an action occurred.

In one embodiment, action log entries are created in the same database 510 as the file table 511 such that file/content rollback can be performed if the file/data/content change results in an error or failure. As such, the action log entry creation in the action log table 516 can be created, in part, to meet durability (e.g., longevity) requirements of a given event/transaction (e.g., write events, or other edit events typically have higher durability requirements than a comment event, or a share event, etc.).

Action log entries can be created for select types of events or all events. For example, events/transactions such as file renames, file uploads may have higher durability requirements than a comment event, or a share event, in a sense that the changes from a file rename/file upload need to be maintained and updated at various respective clients for the relevant collaborators and the implication for missing a file rename or file upload is potentially more severe than missing a comment event or a share event, etc.

In general, action log entries are generally created for actions/events with higher durability requirements. Such a determination can be made by the front ends 502 as to whether a given event type is to be writing into the action log table 516. Action log entries may also be created for all events with durability requirements carried out down stream at event queues stored in the second database (e.g., the database 560 of FIG. 5D). Table 516 shows the action log entries created from the events stored in the file table 511.

The action log entries can be identified by the action ID 517. In addition, each action log entry can be associated with a user (e.g., owner) identifier 518, a data entry 519, and/or a revision identifier 520. The user identifier 518 can identify a user who is to a recipient as a result of an event (e.g., upload file to User 1). The owner identifier 518 represents the owner of the item upon which an action (e.g., represented by action ID 517) occurred and in general, each work item has no more than one owner. The data field 519 can identify the type of action/event (e.g., rename, upload, edit, comment, share, send, download, etc.).

The revision identifier 520 can indicate the version of any change made to a given file (e.g., edit, rename, upload, etc.). In one embodiment, the revision identifier 520 is derived from version tracking mechanisms (e.g., via revision ID 515) inherent to the database 510. The revision identifier 520 can used by remote clients to resolve conflicts in view of potentially conflicting events/transactions. For example, if a file is re-named twice and both events are synchronized/updated at a remote client, the client can use the rename event associated with the latest revision ID to make the necessary updates. This can ensure that the client is updated with the most current change regardless of when the events are read from the queue. Thus, even if the two rename events are writing to the queue for the client out of order, the client can still make the ‘correct’ update using the revision ID in case of conflicting changes.

FIG. 5B depicts one example system block diagram showing action log entries in the action log table 516 being processed by a dispatcher 530. In one embodiment, the dispatcher 530 sends out the action log entries to the processor 540 in parallel. In this embodiment, the action log entries in the action log table 516 are batch written in order by the dispatcher 530 to processors 540. The batch 536 includes log entries for multiple recently occurred to be written to queues for multiple collaborators after processing by the processor 540, which determines the relevant collaborators, for each log entry. The number of actions in the batch can be dynamically determined based on system load and/or to optimize performance.

FIG. 5C depicts a second example system block diagram showing action log entries in the action log table 516 being sorted by owner (e.g., under actor 1 or actor 2) in the dispatcher 530 and then processed in series across users prior to being batched to be sent to the processor 540. In this embodiment, the action log entries are sorted by user in the dispatcher 530 before being batched 536 to be sent to the processor 540. In other words, the events can be grouped by the owner. In some cases, this additional step can be implemented to ensure the correct ordering of events received at a remote client to prevent conflicting changes from being made to a file or content and/or applying the wrong ordering of these changes. After the events are sorted by owner, the events are batch written to the processor 540. The batching is performed by selecting the oldest event across all users and batch writing them to the processor 540.

FIG. 5D depicts an example system block diagram showing how action log entries in the action log table 516 batched from the dispatcher 530 are written, by the processor(s) 540 to queues in a distributed database cluster 560 based on client and collaborator.

The processor 540 analyzes each action/transaction logged in the action log table 516, by for example, processing each row in the table 516 and determining the collaborators to whom each action/transaction is relevant. This determination can be based on user groups, user affiliation with enterprises, user rights/rules, etc. in the cloud-enabled platform such as a collaboration environment. In addition, the processor 540 analyzes each action/transaction and determines the client type category to which each action/transaction is relevant. For example, a re-name event may be relevant to both synchronization clients and real-time web clients, whereas, a comment event may only be relevant to a real-time web client. Once the relevant collaborator to whom to notify, or whose account is to be updated, and the relevant client(s) have been determined, the processor 540 writes the event to the relevant queues.

In general, each queue is specific to one client category type of a given user. For example, all sync clients of user ‘John’ will read from one queue. Each of John's sync clients, which may be installed on different devices maintains its own location in the queue from which to read such that the synchronization or update that is applicable to a specific device/specific sync client is read from the queue in the second repository (e.g., a distribute database cluster, or Hbase 560). Since the queues in the second repository 560 are read only queues, the sync clients or other remote clients cannot modify the queue such that they can be read by other sync clients of the same user so that the necessary changes/updates are applied. In some embodiments, the system can implement one queue per client, or one client per user. In general, any number of other types of mappings can be made to HBase queues.

Since different client type categories are updated with different types of events, user John can have a separate queue for his real-time web clients, and another queue for other types of clients. Maintaining different queues for different client type categories of a user has a further advantage in cleaning up or purging data from the second database 560. Since events/actions written to queues are specific to the category type, during clean-up, the queues can be maintained with different life time durations. For example, queues for the real time web clients can be removed sooner or stored for lesser amount of time than queues for sync clients, due to the nature of events/actions written to the queues. For example, queues for real time web clients can be stored for on the order of a few days, or a few hours, whereas the queues for sync clients can be stored for days, weeks, or months, if needed.

FIG. 6 depicts a block diagram illustrating an example system 600 showing the aggregate of the components described in FIGS. 5A-5D on the server-side of the cloud-based platform for incrementally updating a remote client with occurred events or actions.

The host server 600 can include a host of a collaboration environment can generally be a cloud-based service.

The host server 600 can include, for example, a network interface 602, a front end component 605 having an event type identification engine 606 and a consistency and durability manager, a dispatch engine 615 having a sorting engine 617, a serialization engine 618, a batching engine 619, and a user queue manager 635 having a collaborator identification engine 636, a client selection engine 637, a time sequence manager 638, and a queue writing module 639. The host server 600 is coupled to or includes a database 655 and a database cluster 625. Additional or less components/modules/engines can be included in the host server 600 and each illustrated component.

The network interface 602 can be a networking module that enables the host server 500 to mediate data in a network with an entity that is external to the host server 400, through any known and/or convenient communications protocol supported by the host and the external entity. The network interface 502 can include one or more of a network adaptor card, a wireless network interface card (e.g., SMS interface, WiFi interface, interfaces for various generations of mobile communication standards including but not limited to 1G, 2G, 3G, 3.5G, 4G, LTE, etc.), Bluetooth, a router, an access point, a wireless router, a switch, a multilayer switch, a protocol converter, a gateway, a bridge, bridge router, a hub, a digital media receiver, and/or a repeater.

As used herein, a “module,” “a manager,” a “handler,” a “detector,” an “interface,” a “processor,” a “tracker,” a “detector,” a “generator,” a “launcher,” a “selector,” an “updator,” or an “engine” includes a general purpose, dedicated or shared processor and, typically, firmware or software modules that are executed by the processor. Depending upon implementation-specific or other considerations, the module, manager, hander, or engine can be centralized or its functionality distributed. The module, manager, hander, or engine can include general or special purpose hardware, firmware, or software embodied in a computer-readable (storage) medium for execution by the processor. As used herein, a computer-readable medium or computer-readable storage medium is intended to include all mediums that are statutory (e.g., in the United States, under 35 U.S.C. §101), and to specifically exclude all mediums that are non-statutory in nature to the extent that the exclusion is necessary for a claim that includes the computer-readable (storage) medium to be valid. Known statutory computer-readable mediums include hardware (e.g., registers, random access memory (RAM), non-volatile (NV) storage, to name a few), but may or may not be limited to hardware.

The front end component 605 is able to detect actions in a cloud-based environment (e.g., a collaboration environment hosted by server 600) an identify the event type (e.g., by the event type identification engine 606). Based on the event type, an action log entry can be created in the database 655 in the action log table 658. The action log entry can be created from a file/folder entry 656. The front end component 605 can also determine or estimate the consistency and durability requirements of a given event (e.g., by the consistency and durability manager 607). These requirements can be effectuated through the creation of an action log entry for the associated action/event in the database 655.

The front end component 605 is coupled to multiple users and multiple devices and processes events/actions generated across multiple users, platforms, devices, or enterprises. The action log table 658 generated therefrom is read by the dispatch engine 615 which is able to serialize the events represented by the action log entries stored in the action log table 658. The dispatch engine 615 batches log entries (e.g., by the batching engine 619) from the table 658 and passes the events on to the user queue manager 635 for further processing. One embodiment of the dispatch engine 615 can further include a sorting engine 617 which optionally sorts the action log entries by recipient user or a user whose account is to be updated before being batched for processing by the user queue manager 635.

The user queue manager 635, retrieves each action log entry and is able to analyze the action/event and identify the collaborators (e.g., by the collaborator identification engine 636) who are to be notified of the action/event or whose accounts/contents are to be updated as a result of the action/event. Further, based on the action/event type the client category type (e.g., whether the client is a sync client, real-time web client, mobile client, mobile sync client, email client, etc.) which is to be notified or synchronized is determined by the client selection engine 637. Certain events/actions are only relevant to sync clients, while some may be relevant to both sync clients and web clients.

The time sequence manager 638 is able to associate events with a time stamp or a key. The time stamp or key (which may be a reference to a location in memory or storage) can be used by remote clients to keep track of the events/actions that have been synchronized or read for updating.

FIG. 7 depicts a flow chart illustrating an example process for notifying a remote client of updates in a cloud-enabled platform for each remote client associated with a collaborator in an incremental fashion.

In process 702, an action is detected in the cloud-enabled platform. The action can be performed by any user or collaborator of a user group, organization, or enterprise and can include any action (e.g., upload, comment, share, email, send, download, edit, delete, rename, name, etc.) performed on files, folders, or any content shared, stored, and/or accessed via the cloud-enabled platform, such as an online or web-based collaboration environment.

In process 704, a data change is effectuated as a result of the action in a first database, in the cloud environment, based on the action. In process 706, an action log entry is created from the action. In one embodiment, the action log entry is created in the first database, same as the data change, to enable rollback to previous versions before the data change was effectuated.

In process 708, the collaborator of the user's in the cloud-enabled platform is identified. The collaborator(s) can be identified based on user group information, enterprise affiliation or other group/rules based definition of work groups which determine which users are collaborators to be notified of a given event, or which user accounts are to be updated. In process 710, the remote client of the collaborator which is to be synchronized with the data change as an update is identified.

In process 712, a decision is made as to whether to write the action to the second database in the queue for the remote client based on action type, prior to writing the action to the queue. In addition a decision can be made as to whether to write the action to the second database for the remote client based on client type, prior to writing the action to the queue.

In process 714, the action represented by the action log entry is written to a second database into a queue to be read by the remote client of the collaborator. In general, the queue is specific to a client type of the remote client. The client type can be a synchronization client, a mobile client, or a web-based interface client to access the cloud-enabled platform. A synchronization client can be any client installed on a device, which automatically synchronizes locally stored content with content in the cloud (e.g., in the cloud-enabled platform) such that the changes made by other users or the user of the device from other devices/clients/interfaces can be synced locally at the device. The web-based interface client can be any web interface used by the user to access his/her account with the cloud-enabled platform.

In instances where the collaborator or user utilizes multiple synchronization clients, each of the multiple synchronization clients can read from the queue at locations relevant to the individual remote client. For example, each of the multiple remote clients individually tracks a location in the queue from which each previously read. In general, the queue is a read-only queue such that clients can read from it without making changes such that other clients can still read from the queue and update the client/device as needed and as relevant.

The action can be written to a second queue for a web-application interface to the cloud-enabled platform. The action can also be to a third queue for an audit log. The queue may be associated with a lifetime to be stored in the second database to ensure durability requirements associated with the client type. For example, the lifetime for a queue for a desktop synchronization client can be longer than the life time for a queue for a web-based browser client.

In one embodiment, the action is written to the second queue as a part of a batch of recently occurred actions to be written to queues for multiple collaborators. The number of actions in the batch can be dynamically determined.

In process 716, the remote client of the collaborator reads from the queue in the second database for synchronization. The remote client can read from the queue such that the remote client is updated to reflect the action. For example, the remote client sends a query to the second database for synchronization of the updates specific to the collaborator.

The query can be associated with a timing parameter specified by the remote client such that the updates that are synchronized to the remote client include actions which are more recent than a time referenced by the timing parameter. Similarly, the query can be associated with a parameter specified by the remote client such that the updates that are synchronized to the remote client include actions which are written to the queue after a location referenced b the parameter.

In one embodiment, the remote client updates only the action without updating other actions which have previously been updated at the remote client. In process 718, the remote client is synchronized with updates in a cloud-enabled platform in an incremental fashion. This allows the remote client, such as a synchronization client to efficiently update the local device without the need to perform additional analysis or comparison as to which changes made on the server side have been or have yet to be made on the local device.

FIG. 8 depicts a flow chart illustrating an example process for creating an action log entry with a revision identifier for a client to be updated in time sequential order based on when events occurred via the cloud-enabled platform to prevent conflicts in files or data.

In process 802, an action log having log entries is created in a data repository for events that occurred in the cloud-enabled collaboration platform. Each log entry can be associated with a unique identifier, and where, each log entry can be entered in the action log in an order in which an associated action occurred in the cloud-enabled collaboration platform. In one embodiment, each log entry is created from a file entry stored in the data repository. The data repository can include a relational database such as a SQL database.

In process 804, a log entry in the action log is associated with an event type identifier and a revision identifier. The revision identifier of a given event can be used by the client for conflict resolution. The revision identifier can be derived from version trackers used by the SQL database.

The log entry can be further associated with a user identifier. In some instances, the log entries are sorted based on the user identifiers. In one embodiment, the user identifier is associated with a recipient user whose account is to be updated as a result of the event. In one embodiment, the user identifier can be associated with a user who performed the event or action.

In process 806, an event is represented with the log entry identified by the event type identifier performed, in the cloud-enabled collaboration platform. In process 808, a collaborator to be notified of the event represented by the log entry is identified, for each entry. In process 810, the event is written into a queue for the collaborator in a distributed database cluster to be read by one or more of multiple clients. The distributed database cluster can include non-relational databases. For example, the distributed database cluster is a write-optimized or optimized for sequential reads. In on embodiment, the distributed database cluster is an HBase cluster. In one embodiment, the queue for the collaborator is specific to a client or a client category type used by the collaborator for accessing the cloud-enabled collaboration platform.

In general, different portions of the ordered sequence of events can be sent to different client types or different clients of the collaborator. The client type can include, a web-based client, a desktop synchronization client, a mobile synchronization client, a mobile application, an email notification client, or an enterprise action log of the cloud-enabled collaboration platform. In one embodiment, the event is written to the distributed database cluster as a part of a batch of recently occurred events to be written to queues for multiple collaborators

In process 812, the client reads from the queue of the collaborator in the distributed database cluster to obtain incremental updates in the cloud-enabled collaboration platform from the events logged in the action log. In process 814, Incremental updates in the cloud-enabled collaboration platform are obtained from the events logged in the action log. In process 816, the revision ID of a given event for conflict resolution

FIG. 9 depicts a flow chart illustrating an example process for managing queues based on action type and client type.

In process 902, an action type of an action performed by a collaborator of the user in the cloud-based collaboration service is determined. In process 904, a queue which is uniquely associated with a client category of the clients associated with the user is identified. The client can include cloud-based collaboration service and/or an instance of a desktop synchronization client to synchronize content with the cloud-based collaboration service.

In process 906, the clients of the user, to receive a notification as a result of the action or to perform synchronization with changes that occurred as a result of the action are selected based on the client category and the action type of the action. In process 908, a representation of the action is stored to queues of clients associated with the user in a distributed database cluster. Each of the queues is typically uniquely associated with a client category of the clients associated with the user and the clients of the user are selected based on the client category and the action type of the action, to receive a notification as a result of the action or to perform a synchronization with changes that occurred as a result of the action.

In process 910, subsequently occurring actions are written to the queues of the clients associated with the user in a time ordered fashion. In process 912, additional representations of actions to additional queues of other clients associated with other users of the cloud-based collaboration service are stored in the distributed database cluster.

FIG. 10 depicts a flow chart illustrating an example process for updating multiple clients at one or more devices for a given user with events occurring in a collaboration platform.

In process 1002, a queue stored in a distributed database queried and a location in the queue from which to read is specified. The queue includes entries representing each of a sequence of events which occurred in the collaboration platform that is relevant to the user. In one embodiment, the queue that is queried is specific to client type of the client and is also specific to a user. Each entry can be associated with an action type identifier of a given event; entry can further be associated with a revision identifier, the client uses the revision identifier for conflict resolution at the client device.

In process 1004, the queue is read starting from the location. In process 1006, the client device is updated based on the events that occurred in the collaboration platform upon reading the queue. This is performed in such a manner that previously occurred events which have been updated at the client need not be accessed prior to reading the portions of the queue with those events which have yet to be updated at the client.

In process 1008, the client device is updated based on the events that occurred in the collaboration platform upon reading the queue. The collaboration platform can include a cloud-based service and/or storage platform. In process 1010, another location in the queue from which to begin a subsequent read is stored by the client. In process 1012, multiple clients associated with the client device or different client devices of the user read from the same queue. In process 1014, each of the multiple clients individually track a location in the queue from which to read to reflect updates relevant to the client device on which the client resides.
