Welcome Symas LMDB

Symas LMDB Ultra-fast, ultra-compact key-value embedded data store developed by Symas for the OpenLDAP Project. It uses memory-mapped files, so it has the read performance of a pure in-memory database while still offering the persistence of standard disk-based databases, and is only limited to the size of the virtual address space, (it is not limited to the size of physical RAM)

Check it out!

NeDB fast JavaScript DocDB with MongoAPI!

Please welcome

NeDB

 is a NoSQL database for Node.js in pure javascript. It implements the most commonly used subset of MongoDB's API and is quite fast (about 25,000 reads/s on a 10,000 documents collection with indexing).

Looks like a nice project.
Good luck!
