OverDB is an implementation of the GroupOverview database, based on boltDB (bbolt) and the SSTable format from LevelDB.

OverDB implements the GroupOverview database, which is basically a sorted key-value store, storing (group=>status+description) pairs.

BoltDB is used for metadata and it is used to implement a Writable key-value store.

LevelDB's SSTable is used as a Read-Only key-value store and an Export- and Import-format for the key-value pairs.
