메소드	설명
Close ( ) : void	Closes database connection if exists.
CreateDbConnection ( ) : DbConnection
DeleteMessagesToAsync ( string persistenceId, long toSequenceNr ) : Task	Asynchronously deletes all persisted messages identified by provided persistenceId up to provided message sequence number (inclusive).
ReadEvents ( object queryId, IEnumerable hints, IActorRef sender, Action replayCallback ) : Task	Performs
ReadHighestSequenceNrAsync ( string persistenceId, long fromSequenceNr ) : Task	Asynchronously reads a highest sequence number of the event stream related with provided persistenceId.
ReplayMessagesAsync ( string persistenceId, long fromSequenceNr, long toSequenceNr, long max, IActorRef sender, Action recoveryCallback ) : Task	Asynchronously replays all requested messages related to provided persistenceId, using provided sequence ranges (inclusive) with max number of messages replayed (counting from the beginning). Replay callback is invoked for each replayed message.
WriteMessagesAsync ( IEnumerable messages ) : Task>	Asynchronously writes all persistent messages inside SQL Server database. Specific table used for message persistence may be defined through configuration within 'akka.persistence.journal.sql-server' scope with 'schema-name' and 'table-name' keys.
