ForestDB

ForestDB is a fast key-value storage engine that is based on Hierarchical B+-Tree based Trie, called HB+-Trie, and was written in C++ and developed by Couchbase Caching and Storage Team to provide a scalable and high performance storage layer for Couchbase NoSQL database.

ForestDB can support efficient indexing and retrieval on a large number of variable-length keys, in terms of block device I/O operations. As discussed in Performance section, it especially shows much better I/O performance in Solid-State Drives (SSDs). We have tested ForestDB on various server OS environments (Centos, Ubuntu, Mac OS x, Windows) and mobile OSs (iOS, Android)
