Redis server notes

redis caches server notes

redis is a high-performance key-ES6en storage system that can act as a caching framework and queue

But since it is an in-memory system, the data will still be stored in the database

As a caching framework:

create/updae/delete-- save to both redis and database

query- Check from redis first, no record from the database, and put a copy of the results from the database to redis

As a cache queue:

2. Store the object Object in redis. memcache access objects are serialized and deserialized

Use common serialization, deserialization (frequent consume cpu, use Google Protocol Buffer, stream objects in base 2)

Or use json storage (Alibaba's ES38en-ES39en)

3, java using redis client 1 is generally: jedis

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

4. My understanding of redis queue:

Important data: First to the database, then to redis

Data requiring high response times: writes to the cache and then to the database via message queues
