How redis solves data consistency
Redis provides two consistency models to maintain copy data consistency: strong consistency (sync) ensures that the write operation is completed only after copying to all slave nodes; eventual consistency (async) ensures that the write operation is completed after the write operation on the master node Consider it done, sacrificing consistency for performance.

How redis solves data consistencyRedis provides two consistency models to maintain replica data consistency: strong consistency (SYNC) ensures that write operations are completed only after being replicated to all slave nodes; eventual consistency (ASYNC) ensures that write operations are completed only after being copied to all slave nodes. Consider it done, sacrificing consistency for performance. In addition, optimistic locking and atomic operation mechanisms can further enhance client consistency. Choosing a consistency model should be based on the trade-off between the application's consistency requirements and performance sensitivity.
How to write redis read and write separation codeUse Redis to implement read-write separation code by connecting a write server and multiple read servers: 1. Write operations are performed using the write server client; 2. Read operations are performed using the read server client; 3. Ensure data consistency needs to be performed regularly Synchronize data between write server and read server.
How to realize redis read and write separationRedis read and write separation is implemented by routing read requests to the slave node and routing write requests to the master node. The specific steps are as follows: 1. Create a master-slave replication environment; 2. Configure the read-write separation client; 3. Route read requests to the slave node; 4. Force write requests to the master node; 5. Synchronize master-slave data.
How to use redis as a cache serverRedis as a cache server answer: Redis is an open source, high-performance, distributed key-value store that can be used as a cache server. Reason: High Performance: Store data in memory for fast access. Low latency: Optimized data structures and operations to minimize latency. Scalability: Easy to shard and cluster to adapt to high loads. Durability: Data can be persisted to disk to ensure data security. Rich features: Provides multiple data types, multi-level caching and publish/subscribe functions.
