 可搜索的分布式Key-Value存储 HyperDex

HyperDex是一个分布式,可搜索的Key-value存储。它具有以下特性:

  • Fast HyperDex has lower latency and higher throughput than most other key-value stores.

  • Searchable HyperDex enables lookups of non-primary data attributes. Such searches are implemented efficiently and contact a small number of servers.

  • Scalable HyperDex scales as more machines are added to the system.

  • Consistent The value you GET is always the latest value you PUT. Not just "eventually," but immediately and always.

  • Fault tolerant HyperDex handles failures. Data is automatically replicated on multiple machines so that failures do not cause data loss.

1.分布式KV store,系统性能能够随节点数目线性扩展
2. 吞吐和延时都能秒杀现在风头正劲的MonogDB,吞吐甚至强于Redis
3.使用了hyperspace hashing技术,使得对存储的K-V的任意属性进行查询成为可能
