Does redis need to separate reading and writing?

Does redis need to separate reading and writing?

Yes, read-write separation is often necessary when using Redis to optimize performance and improve availability. The benefits of read-write separation include: reducing the load on the main server, improving read performance, improving availability, simplifying maintenance, and implementation methods including master-slave replication and the use of middleware. Separation of reading and writing is required in high-concurrency reading and writing scenarios, when high reading performance requirements are required, and when high availability is required. It should be noted that write requests can only be sent to the master server. The slave server data may be slightly delayed, and data consistency issues need to be considered.
