Redis Master Node Labeling for Automatic Failover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In Redis database systems, switching from a master Redis node to a new master Redis node after failure requires manual modification of address information in clients, which reduces storage efficiency during information storage.
Innovation Solution
A method and apparatus for information processing that automatically searches for a storage node with a master storage label within a storage cluster, allowing direct storage of information and automatic reconfiguration of node roles without manual address modifications.

1Reliability
If manual modification of address information is performed after master Redis failure, then storage reliability is maintained through failover, but storage efficiency deteriorates due to manual intervention requirements
Solution Approach 1:
The system performs automatic failover where the slave Redis node autonomously becomes the new master node without requiring manual address modification. The client system automatically detects the master node failure and redirects requests to the promoted slave node, enabling the system to serve itself during failover events.
Solution Approach 2:
The slave Redis node is pre-configured and ready to become master before failure occurs. The address information and node configuration are prepared in advance, so when failover is needed, the transition can occur immediately without manual intervention to modify address information.
2Manufacturing precision
If manual address modification is required after node switching, then correct routing is achieved, but time consumption increases due to manual operations
Solution Approach 1:
The system implements automatic detection and feedback mechanisms where the client monitors the master Redis node status. When failure is detected, the system automatically receives feedback about the new master node address and updates its routing information without manual intervention, ensuring both accuracy and speed.
Solution Approach 2:
The new master node address information is prepared and validated in advance as part of the failover configuration. When switching occurs, the routing information is already ready to be applied immediately, eliminating the time required for manual address modification while maintaining routing accuracy.

AI summary
Embodiments of the present application provide an information processing method and apparatus, and a storage medium. The method comprises: under the condition that information to-be-stored is received, searching a storage cluster for a first storage node containing a main storage label, and storing said information into the first storage node, the main storage label being, when a node of a main storage type is determined from the storage cluster, a label allocated to the node of the main storage type. By means of the technical solution, the purpose of improving the storage efficiency during information storage is achieved.
