Redis 's master-slave replication is very powerful, a master can have multiple slave, and a slave can have multiple slave, so go on, Form a powerful multi-level server cluster architecture . The implementation steps are as follows :1.

Redis is an in-memory database that supports persistence, which means that Redis often needs to synchronize in-memory data to disk to ensure persistence. Redis supports two persistence modes, one is snapshotting (snapshot) is the default, and the

The Redis memory management method supports Tcmalloc,jemalloc,malloc three memory allocations, memcache using memory allocation methods such as Slabs,malloc.The simple point, Redis, is to use the side of the application, using the field to apply
