class DbStorageMulti extends DbStorage with FlagCloseable with NamedLogging
DB Storage implementation that allows multiple processes to access the underlying database and uses a pool of write connections which are guarded by an exclusive main lock to ensure a single writer instance.
Periodically checks the activeness of the write connection pool and if the activeness changes executes the
onActive or onPassive callbacks.
