Abstract
A method of optimizing propagation of non-persistent messages from a source database management system (DBMS) to a destination database management system (DBMS) is described and provided. The method comprises receiving one or more nonpersistent messages from a source non-persistent message queue of the source DBMS at a destination non-persistent message queue of the destination DBMS. The nonpersistent messages are consumed from the destination non-persistent message queue such that consumed non-persistent messages are removed from the destination non-persistent message queue. Further, at least a portion of the non-persistent messages are spilled from the destination non-persistent message queue to a destination persistent message queue of the destination DBMS based on at least one parameter selected from a group consisting of a sparseness factor, number of nonpersistent messages in the destination non-persistent message queue, and amount of memory resources utilized by the destination non-persistent message queue. Moreover, to the source DBMS is sent an acknowledgment including a watermark indication of consumed non-persistent messages from the destination non-persistent message qu…
