Redis v3.2.2发布下载，Redis 是完全开源免费的，遵守BSD协议，是一个高性能的key-value数据库。
特点：
Redis支持数据的持久化，可以将内存中的数据保持在磁盘中，重启的时候可以再次加载进行使用。 Redis不仅仅支持简单的key-value类型的数据，同时还提供list，set，zset，hash等数据结构的存储。 Redis支持数据的备份，即master-slave模式的数据备份。优势：
性能极高 Redis能读的速度是110000次/s,写的速度是81000次/s 。 丰富的数据类型 Redis支持二进制案例的 Strings, Lists, Hashes, Sets 及 Ordered Sets 数据类型操作。 原子 Redis的所有操作都是原子性的，同时Redis还支持对几个操作全并后的原子性执行。 丰富的特性 Redis还支持 publish/subscribe, 通知, key 过期等等特性。 更新日志Bug修复
1. There was a bug in the List type implementation, able to cause the
crash of the server under certain (non trivial to replicate) circumstances
when the LSET command was used. Now the bug is fixed and a new stress tester
that was able to easily trigger the bug was added to the test suite.
2. Redis Sentinel, when monitoring multiple masters, could crash after
a Sentinel address update event.
3. Redis Sentinel now checks slaves INFO state more often when disconnected.
This is not really a bug fix, but may allow to more easily detect that
a slave is able to fail over its master reducing certain delays.
4. It was possible, under a variety of conditions, that the AOF and RDB children
process could spawn at the same time. This is known to trash disk I/O,
AOF performances, and to ultimately create latency in the Redis server.
Normally Redis avoids to have the two writing children at the same time, but
there were edge cases discovered by Oran Agra (that also co-authored the
fix with me) where the double-fork could happen. In order to fix this bug
non trivial changes to the replication code were operated, however it was
important to back port this fix into 3.2.2 because the bug could lead to
bad latency experiences in certain cases.
5. Many GEORADIUS bugs are now fixed \o/. This started as a failing CI
test. I grepped for more clues and there were a number of random failures
in the points reported by GEORADIUS. The errors were found to be related
to three different bugs (one of these was a bug in the test itself).
It's not a critical bug: the effect is to, sometimes, don't report objects
that are near the radius, but only with specific sets of coordinates
and radius settings. However now the issues are fixed and the error
vectors were added as regression tests.
新功能
1. Now slaves support the slave-announce-ip and slave-announce-port options.
Using these features a slave can be reported by the master `INFO` output
and `ROLE` command as having arbitrary IP and port. This allows to have
Sentinel deployments when working with containers or NAT-ed environments
more easily.
2. The RDB check utlity is now part of Redis and uses the same RDB code that
Redis uses in order to load the dataset in memory, so a given version
of Redis is always able to check the RDB it produced... without another
external check tool which is supposed to be taken in sync with the
rdb.c implementation. This in turn also means that the new RDB checking
is able to spot more complex bugs, since it really loads the dataset
instead of just skipping bytes.
