elasticell's Introduction

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

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 ？

is elasticell in production in any company ?

[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=<127.0.0.1:20801>
2018/01/21 13:00:52.522669 [fatal] bootstrap: get cluster id from pd failure, pd=<[127.0.0.1:20801 127.0.0.1:20802 127.0.0.1:20803]>, 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.

找个架构看起来和tikv一样，有什么优势吗？

可否讲一下elasticell和pika以及ssdb的优缺点？

编译cell报错

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？

启动redis_proxy出错

还在开发吗？二月份后更新就很少了啊

请问中文文档在哪里
