TokuMX
TokuMX is an open-source distribution of MongoDB which, among other things, replaces the default B-tree data structure found in the basic MongoDB distribution with a Fractal Tree index. It is a drop-in replacement for MongoDB (applications will run "as is") that offers the scalability and performance improvements associated with Fractal Tree indexing. It also adds support for document-level locking, transaction support with ACID and MVCC, and replication optimization; it does not support full-text search.
