MongoMVCC implements the Multiversion Concurrency Control paradigm (MVCC) on top of MongoDB. MVCC allows lock-free concurrent database access. Since every connection gets its own database snapshot (also known as version or commit) database reads and writes can be performed concurrently without compromising the data’s consistency.
The MVCC implementation in MongoMVCC has mostly been inspired by Git and so it uses almost the same terms and techniques. With MongoMVCC you can checkout multiple branches of your database, create consistent commits and review the history of your data. Advanced features like merging or rebasing will follow in the future.
