发布说明

Redis2.8引入的更改点（以上转载）

• Redis Cluster: a distributed implementation of a subset of Redis.

• New “embedded string” object encoding resulting in less cache

• misses. Big speed gain under certain work loads.

• AOF child -> parent final data transmission to minimize latency due

• to “last write” during AOF rewrites.

• Much improved LRU approximation algorithm for keys eviction.

• WAIT command to block waiting for a write to be transmitted to

• the specified number of slaves.

• MIGRATE connection caching. Much faster keys migraitons.

• MIGARTE new options COPY and REPLACE.

• CLIENT PAUSE command: stop processing client requests for a

• specified amount of time.

• BITCOUNT performance improvements.

• CONFIG SET accepts memory values in different units (for example

• you can use “CONFIG SET maxmemory 1gb”).

• Redis log format slightly changed reporting in each line the role of the

• instance (master/slave) or if it’s a saving child log.

INCR performance improvements.
