Detailed Description

This file implements OnDiskKeyValueDB, an ondisk key value database.

The KeyValue database file is named actions.<version> inside the CAS directory. The database stores a mapping between a fixed-sized key and a fixed-sized value, where the size of key and value can be configured when opening the database.
