The disclosure is filed based on and claims the benefit of priority of the Chinese Patent Application No. 202111542702.9, filed on Dec. 16, 2021, and entitled “Information processing method and device and storage medium”, the disclosure of which is incorporated by reference herein in its entirety.
Embodiments of the disclosure relate to the field of database, in particular to a method and apparatus for information processing and a storage medium.
Remote Dictionary Server (Redis) is a high-performance, open-source, and key-value pair database with high read and write performance. Redis can save key-value pair data stored in a memory to a hard disk persistently. Different persistence modes can be configured by a user according to actual usage scenarios. In order to improve a storage reliability of Redis, a common choice is to set up a master Redis and a slave Redis in different servers. When the master Redis fails, the slave Redis is switched into a new master Redis to continue to provide storage services to the outside.
However, after switching the slave Redis into the new master Redis, before performing a storage operation, it is necessary to manually modify address information of the original master Redis stored in a client to address information of the new master Redis, which reduces a storage efficiency during information storage.
Embodiments of the disclosure provide a method and apparatus for information processing and a storage medium, which can improve the storage efficiency during information storage.

It should be understood that the specific embodiments described herein are intended only to explain the disclosure and do not constitute a limitation of the disclosure.
An embodiment of the disclosure provides a method for information processing, executable by an apparatus for information processing.
At S101, a storage cluster is searched for a first storage node containing a master storage label in response to receiving information to-be-stored, and the information to-be-stored is stored into the first storage node. The master storage label is a label allocated to a node of a master storage type when the node of the master storage type is determined from the storage cluster.
In the embodiment of the disclosure, the apparatus for information processing searches the storage cluster for the first storage node containing the master storage label in response to receiving the information to-be-stored, and stores the information to-be-stored into the first storage node. The master storage label is a label allocated to a node of a master storage type when the node of the master storage type is determined from the storage cluster.
The method for information processing proposed by the embodiment of the disclosure can be applied to the scenario where information is stored in the storage node.
In an embodiment of the disclosure, the first storage node containing the master storage label is generated before receiving the information to-be-stored. Specifically, the master storage label corresponding to the node of the master storage type is allocated to the first storage node in response to determining the node of the master storage type in the storage cluster to be the first storage node.
It should be noted that the node of the master storage type in the storage cluster is used for providing storage services to the outside, and correspondingly, there is also a node of a slave storage type in the storage cluster. The node of the slave storage type does not need to provide services to the outside, but needs to copy information from the corresponding node of the master storage type in real time in order to keep information synchronization between the node of the master storage type and the node of the slave storage type, so that subsequent storage tasks can be processed by the node of the slave storage type when the node of the master storage type is restarted in response to detecting an abnormality.
It should be noted that one node of the master storage type corresponds to one or more nodes of the slave storage type. The specific correspondences can be determined according to the actual situation, which is not specifically limited in the disclosure.
In the embodiment of the disclosure, after storing the information to-be-stored into the first storage node, if an abnormality is detected in the first storage node, it is necessary to replace the node of the master storage type to provide the subsequent storage services at this time. Specifically, the storage cluster is searched for a second storage node corresponding to the first storage node in response to detecting an abnormality in the first storage node, and the master storage label is set for the second storage node. The first storage node is started through new address information in response to acquiring the new address information allocated to the first storage node, and the first storage node is set as a node of a slave storage type through the new address information in response to a completion of the starting of the first storage node.
In the embodiment of the disclosure, the address information is an Internet Protocol Address (IP address).
It should be noted that
It should be noted that the number of sentinels in the monitoring cluster may be one or more, and the specific number is determined according to the actual situation, which is not specifically limited in the disclosure.
It should be noted that the second storage node is one of the nodes of the slave storage type corresponding to the first storage node. Since the first storage node may correspond to one or more nodes of the slave storage type, one of the multiple nodes of the slave storage type may be randomly selected as the second storage node when one storage node corresponds to multiple nodes of the slave storage type.
In the embodiment of the disclosure, the new address information is reallocated for the first storage node by a first instance. Specifically, the first instance is triggered to allocate the new address information for the first storage node when the first instance corresponding to the first storage node has been restarted.
It should be noted that, since the storage node in the disclosure is a containerized Redis, the address information of the storage node is virtual address information. When the instance where the containerized Redis is deployed is restarted in response to detecting an abnormality, the address information will be reallocated for the containerized Redis.
In a practical application,
1. The monitoring cluster monitors the storage cluster.
It should be noted that, since the address information of each storage node in the storage cluster is stored in the monitoring cluster, a working state of each storage node in the storage cluster can be monitored in real time.
2. An operation and maintenance module monitors the monitoring cluster.
It should be noted that the operation and maintenance module is configured to assist the monitoring cluster in switching between the node of the master storage type and the node of the slave storage type.
3. The monitoring cluster triggers the switching between the node of the master storage type and the node of the slave storage type in response to detecting that the instance where the master storage node is deployed is restarted due to an abnormality in the master storage node in the storage cluster.
It should be noted that, at this time, due to the restart of the instance where the master storage node is deployed, the new address information will be reallocated to the master storage node. At this time, since only old address information of the master storage node is stored in the monitoring cluster, the master storage node cannot continue to be monitored. The storage cluster is searched for the slave storage node corresponding to the master storage node, and the slave storage node is regarded as a new master storage node in the storage cluster.
4. The operation and maintenance module allocates a master storage label to the new master storage node in response to detecting that the monitoring cluster has completed the switching between the node of the master storage type and the node of the slave storage type.
It should be noted that at this time, the apparatus for information processing directly sends information to-be-stored to the new master storage node containing the master storage label for storage when receiving the information to-be-stored.
5. The operation and maintenance module acquires the new address information of the original master storage node from a preset database.
It should be noted that the preset database may be a distributed key-value database ETCD, and the specific preset database may be determined according to the actual situation, which is not specifically limited in the disclosure.
It should be noted that the new address information of the original master storage node in the preset database is acquired by an address information detection module. The address information detection module is configured to monitor the instance where the storage node is deployed. After the instance is restarted and new address information is reallocated for the storage node, the address information detection module will acquire the new address information and store it in the ETCD correspondingly, so that the operation and maintenance module can acquire the new address information from the preset database.
It should be noted that when the operation and maintenance module acquires the new address information of the original master storage node from the preset database, it means that the restarting of the instance where the original master storage node is deployed has been completed.
6. The operation and maintenance module starts the original master storage node in the instance, and allocates a slave storage label to the original master storage node.
It should be noted that, when the operation and maintenance module acquires the new address information of the original master storage node from the preset database, it means that the restarting of the instance where the original master storage node is deployed has been completed, so the original master storage node in the instance can be started. After the starting of the original master storage node is completed, the slave storage label is allocated to the original master storage node to indicate that the original master storage node is a node of the slave storage type in the storage cluster at this time, and the original master storage node needs to copy information from the new master storage node in real time in order to keep information synchronization.
7. The operation and maintenance module transmits the new address information of the original master storage node to the monitoring cluster, so that the monitoring cluster can monitor the original master storage node based on the new address information of the original master storage node.
It should be noted that the operation and maintenance module needs to clear historical address information of the original master storage node stored in the monitoring cluster before transmitting the new address information of the original master storage node to the monitoring cluster, and then transmits the new address information.
The embodiment of the disclosure provides a method for information processing. The method includes: searching the storage cluster for the first storage node containing the master storage label in response to receiving the information to-be-stored, and storing the information to-be-stored into the first storage node. The master storage label is a label allocated to a node of a master storage type when the node of the master storage type is determined from the storage cluster. With the above solution, the master storage label is allocated to the storage node, and the master storage node for storing the information to-be-stored can be directly searched from the storage cluster according to the master storage label in response to receiving the information to-be-stored, thereby avoiding the situation in the related art that it is necessary to manually modify address information of a new storage node in the client after switching the slave storage node to the new master storage node in response to detecting an abnormality in the master storage node, and thus improving the storage efficiency during information storage.
