Abstract: In an example embodiment, to improve performance, a solution is provided that removes the bottleneck associated with a single events table. Specifically, the solution provides for three events tables rather than one table. Two of the three tables are domain event outbox tables that are parallel and equivalent to each other. The third table is a domain event indication table, which records which of the domain event outbox tables is in a serve mode versus a maintain mode. At any point in time, one of the two domain event outbox tables is in serve mode while the other is in maintain mode. Serve mode is used for event insert, update, and query, while maintain mode is used for event purge.
