摘要： Systems and methods are provided for managing database updates in an environment in which data parity is to be maintained between multiple databases. Notifications regarding database events, such as data update operations that occur in a particular database, may be generated so that other databases and systems can perform corresponding data update operations. The notifications may be generated, consumed, and acted upon asynchronously with respect to each other. Such asynchronous propagation of database events provides improved performance and increased reliability over synchronous propagation.
