After around 12 million events are published, a sudden drop can be observed in receiver performance that can be considered as the break point upper limit of MySQL event store. In order to continue receiving events without a major performance degradation data has to be purged periodically before it reaches the upper limit. See https://docs.wso2.com/display/DAS310/Purging+Data for more information on configuring data purging.

Another type of event store such as HBase event store should be used when data purging is not possible.
