The distribution threads put the destination address on the replication that needs to be propagated. The distribution threads work in parallel to clear the input queue.

The distribution threads work within the DBMS Server to take the information from the input queue and expand it to fully specify what data needs to be replicated to which targets. The expanded information is stored in the distribution queue. The distribution threads do not perform any replication; they merely prepare data for replication by the Replicator Server. However, no data is expanded to the distribution queue if the threads are not configured. There can be a number of threads in each DBMS Server.
