Elastic Key-Value Storage With Strong Consistency and Reliability


Build Status Go Report Card Project Status

What is Elasticell?

Elasticell is a distributed NoSQL database with strong consistency and reliability.

  • Compatible with Redis protocol Use Elasticell as Redis. You can replace Redis with Elasticell to power your application without changing a single line of code in most cases(unsupport-redis-commands).

  • Horizontal scalability Grow Elasticell as your business grows. You can increase the capacity simply by adding more machines.

  • Strong consistent persistence storage Elasticell put your data on multiple machines as replication without worrying about consistency. Elasticell makes your application use redis as a database and not just only the cache.

  • High availability All of the three components, PD, Cell and Proxy, can tolerate the failure of some instances without impacting the availability of the entire cluster.

  • Question about development mode

    Question about development mode

    It's the interesting project that I have tried the same thing before(base on LogCabin and rocksdb, redis-like API), unfortunately, my project is not going on.

    Does it will continue to develop and keep open source by business company(like TiDB or CockroachDB) or use other development mode ?

  • 近期也在参考multi-raft实现,想了解下elasticell的现状及相关问题


    Hi,目前我们也在参考multi-raft相关的实现,感觉elasticell这个项目很有参考意义,就是有以下几个问题想了解下: (1)elasticell现在是否有用到过生产环境? (2)近期维护也变的很少了,是有什么原因?项目已经稳定了还是没有时间更新了。 (3)有没有什么已知的性能瓶颈或者是坑?

    [Bug] cell cannot bootstrap successfully in the quick-start example.

    Info in cell1.log: 2018/01/21 13:00:52.522075 [info] pd-client: connect to pd server succ, addr=<> 2018/01/21 13:00:52.522669 [fatal] bootstrap: get cluster id from pd failure, pd=<[]>, errors:rpc error: code = 2 desc = not leader

    Cell1 cannot bootstrap successfully, resulting in cell2 and cell3 cannot elect a leader. This situation happens occasionally.
