TokuMX – High-Performance MongoDB Distribution

TokuMX is a high-performance version of MongoDB. It is an open-source project by Tokutek, a database company that focuses on Big Data solutions. TokuMX is a more performant than MongoDB and has greater operational efficiency. Tokutek claims on their homepage:

"TokuMX is a drop-in replacement for MongoDB, and offers 20X performance improvements, 90% reduction in database size, and support for ACID transactions with MVCC."

TokuMX introduces patented Fractal Tree indexing technology (Technology Overview in PDF), which improves upon MongoDB's default B-tree indexing. Fractal Tree indexing is based on cache-oblivious algorithm and it implements the same operations as a B-tree. Fractal Tree indexes uses large, less frequent writes instead of small and rapid ones, which gives a benefit for compression and insertion performance.

Key features overview:



Recently Tokutek released TokuMX version 1.4, which brings us improvements to MongoDB sharding and replication among other useful features. For more information on this release, please, check out full release notes.

TokuMX open-source engine can be found on Github as Tokutek/mongo (GNU General Public License). There is also an Enterprise version with proprietary EULA. To obtain Enterprise version, a subscription must be purchased. It gives customers the following benefits: Technical Support, Onboarding Call and access to Advanced Tools (e.g., Hot Backup).

How TokuMX Gets Great Compression for MongoDB

NeDB - Embedded datastore for node.js

NeDB

NeDB is embedded persistent database for Node.js, written in Javascript, with no dependency (except npm modules of course). You can think of it as a SQLite for Node.js projects, which can be used with a simplerequire statement. The API is a subset of MongoDB's. You can use it as a persistent or an in-memory only datastore.

NeDB is not intended to be a replacement of large-scale databases such as MongoDB! Its goal is to provide you with a clean and easy way to query data and persist it to disk, for web applications that do not need lots of concurrent connections, for example a continuous integration and deployment server and desktop applications built with Node Webkit.
