Redis cache server notes

Redis is a high-performance key-value storage system that can be used as a caching framework and queue

But because it is an in-memory system, the data has to be stored in the database.

As a caching framework:

Create/updae/delete--- is saved to both redis and database

Query-- first checked from redis, no record before from the database, and also put a copy of the results from the database to redis

As a cache queue:

2. How to store the object Object in redis? Memcache access objects are serialized and deserialized

Use general serialization, deserialization (frequently consume cpu, use Google Protocol Buffer to type objects into binary streams)

Or use json storage (Alibaba's fast-json)

3. The client that java uses redis is generally jedis.

The native interface of jedis only supports basic data types and String, byte []

4. My understanding of the redis queue:

Important data: save to the database first, then to redis

Data that requires high response time: write to the cache first, and then write to the database through the message queue
