Badger is a simple, fast embeddable database written purely in the Go language. It has been developed by Dgraph Labs and is available under the open source licence. It is compatible with BSD, Linux, OS X, Solaris and Windows operating systems. It is designed to be very powerful in writing and reading in the same time. Badger uses Multi-Version Concurrency Control (MVCC) and supports transactions. It triggers transactionally and competitively with the serial guarantee of isolated snapshots.
