MySQL Cache server-redis

Redis is a high-performance Key-value database. Redis data is cached in memory and periodically writes the updated data to disk or writes the modification to the appended record file, and Master-slave (master/Slave) synchronization is implemented on this basis.

Cache Read Process:

1, first to the cache to check the data

2, the cache does not exist in the actual data source fetch, take out and put into the cache

3, the next time to retrieve the same information can be directly from the cache

Cache update Process:

1. Update the database

2. Make the cache expire or fail, which will cause the next query data to be detected in the cache and re-run from the database.
