badger - 2.2007.2-3+b9 main

BadgerDB is an embeddable, persistent and fast key-value (KV)
database written in pure Go. It is the underlying database for Dgraph
(https://dgraph.io), a fast, distributed graph database. It's meant
to be a performant alternative to non-Go-based key-value stores like
RocksDB. Project Status [Jun 26, 2019] Badger is stable and is being
used to serve data sets worth hundreds of terabytes. Badger supports
concurrent ACID transactions with serializable snapshot isolation
(SSI) guarantees. A Jepsen-style bank test runs nightly for 8h, with
--race flag and ensures the maintenance of transactional guarantees.
Badger has also been tested to work with filesystem level anomalies,
to ensure persistence and consistency.
