Buildbot stores its state in a database, using the Python DBAPI to access it.
A database is specified with the buildbot.db.dbspec.DBSpec class, which
encapsulates all of the parameters necessary to create a DBAPI connection. The
DBSpec class can create either a single synchronous connection, or a twisted
adbapi connection pool.
Most uses of the database in Buildbot are done through the
buildbot.db.connector.DBConnector class, which wraps the DBAPI to
provide purpose-specific functions.
The database schema is managed by a special class, described in the next section.
