With Replication Server 15.1, you can now save the distributor (DIST) status of a distributor thread in the RSSD.
A DIST thread reads transactions from the inbound queue and writes replicated transactions into the outbound queue. A DIST thread is created when Replication Server connects to the primary database, and can be suspended or resumed manually, or through a Replication Server configuration. Resuming and suspending a DIST thread modifies the DIST status of the thread.
DIST status recording allows the DIST thread to retain its status even after a Replication Server has been shut down.
For more information about DIST status recording, see the Replication Server Reference Manual.
