A reduction in the throughput is observed as shown below after 1200000 events in both DAS receiver nodes. This reduction is caused by limitations of MySQL. The receiver performance variation of the second node of the 2 node receiver cluster is as given below. As the initial buffer filling in receiver queues give very high receiver performance at the beginning of the event publishing, event rate after the first 1200000 events was considered for the following graph.

After around 30 million events are published, a sudden drop can be observed in receiver performance that can be considered as the break point of MySQL event store. Another type of event store such as HBase event store should be used when the receiver performance has to be maintained unchanged. |
