#Codis - yet another fast distributed solution for Redis
Codis is a proxy based high performance Redis cluster solution written in Go/C, an alternative to Twemproxy. It supports multiple stateless proxy with multiple redis instances and is engineered to elastically scale, Easily add or remove redis or proxy instances on-demand/dynamicly.
Codis is production-ready and widely used at wandoujia.com and many companies. You can see Codis Releases for latest and most stable realeases.
##Major Changes in 2.0 In Codis 2.0, we:
- Redesign the request dispatcher, now pipeline and mget/mset requests are much faster than ever!
- Codis-server (forked redis) is upgrated to 2.8.21. It brings bugfix from upstream redis and also has optimizations, for example, lower memory consumption and faster migration.
- Optimize the zk connection, it is more stable now.
- Migration (and autorebalance) tasks are saved on zk, it will be continued automatically when the dashborad is restarted.
##Features
- Auto rebalance
- Extremely simple to use
- Support both redis or rocksdb transparently
- GUI dashboard & admin tools
- Supports most of Redis commands, Fully compatible with twemproxy(https://github.com/twitter/twemproxy)
- Native Redis clients are supported
- Safe and transparent data migration, Easily add or remove nodes on-demand.
- Command-line interface is also provided
- RESTful APIs
- Install go & ZooKeeper
- go get -d github.com/wandoulabs/codis
- cd $GOPATH/src/github.com/wandoulabs/codis
- ./bootstrap.sh
- cd sample
- follow instructions in usage.md
