Facebook Announces Apollo, a New NoSQL Database for On-line Low Latency Storage
Facebook, announced Apollo, Facebook’s Paxos-like NoSQL database. Written in C++11 on top of the Apache Thrift 2 RPC framework, Apollo is a hierarchical storage system where all the data is split into shards, very much analogous to region servers in HBase.
Apollo is still in development and hasn’t been open-sourced though Johnson did state that doing so was something Facebook were looking into and would like to do.
