How to use redis as a cache server

Redis 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.

How redis solves data consistency

Redis 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 does redis ensure double-write consistency with the database?

In order to ensure data consistency in double writing between Redis and the database, the following strategies can be adopted: 1. Sequential update: write to Redis first, then write to the database if successful, and roll back Redis if failed; 2. Transaction update: write to Redis and Database writes are performed as an atomic operation; 3. Pipeline update: combine multiple write operations into one atomic operation; 4. Asynchronous replication: use Redis as an asynchronous replication source to copy data changes to the database; 5. Batch processing Write: Use Redis as a buffer to batch commit changes to the database at regular intervals. The choice of strategy depends on system requirements such as real-time performance, throughput, and reliability.

How to separate reading and writing in redis

Adopting a read-write separation architecture, by creating a master-slave replication group, write operations are handed over to the master instance, and read operations are handed over to the slave instances, thus improving the performance and availability of Redis.

How to read data in redis

Redis provides a variety of data reading methods, including: GET (single key value reading), MGET (batch key value reading), HGET (hash table key value reading), HGETALL (hash table all key value reading) Fetch), LRANGE (list range data reading), ZRANGE (ordered set range member reading), ZRANGEBYSCORE (ordered set fractional range member reading). The data read by these methods are all in binary format and need to be converted according to the data type. Non-existing keys return nil.
