DAS Performance Test Round 3: RDBMS (MySQL)

Receiver node Data Persistence Performance

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.

With MySQL RDBMS event store

DAS data persistence was measured by publishing to 2 load balanced receiver nodes with MySQL database.
