How does Redisson address the issue of master-slave consistency?

Redisson is a Java client for interacting with Redis, but it does not address the issue of master-slave consistency. Typically, master-slave consistency problems arise from Redis’s replication mechanism, where if the master node fails, the slave nodes may not remain in sync with the master node.

To address the issue of master-slave consistency, the following solutions can be considered:

1. Utilizing Redis Sentinel: Redis Sentinel is an official high availability solution provided by Redis. It monitors the status of master and slave nodes and automatically switches a slave node to become the master node when the master node fails. Redisson can be used in conjunction with Redis Sentinel by configuring the Redis Sentinel address to achieve master-slave switching.
2. Utilize Redis Cluster: Redis Cluster is the official distributed solution offered by Redis, allowing data to be distributed across multiple nodes for high availability and load balancing. Redisson can be used in conjunction with Redis Cluster by configuring the addresses of the Redis Cluster nodes to achieve data distribution and failover mechanisms.
3. Custom implementation: For a more advanced solution for achieving master-slave consistency, custom development can be done based on Redisson. For example, functionalities such as data synchronization, fault detection, and automatic switching can be implemented on top of Redisson to ensure master-slave consistency.

In conclusion, Redisson itself doesn’t offer a solution for achieving master-slave consistency, but it can be used in conjunction with solutions like Redis Sentinel and Redis Cluster, or customized development can be done to achieve master-slave consistency.
