Deprecation Notice MySQL Streamer is now archived, but we're glad you're checking out Yelp Engineering's work on GitHub! If you'd like to learn more about what we're up to now, please visit our tech blog to get the latest scoop on Yelp Engineering.

If you'd like to setup a MySQL CDC connector to Kafka, check out Debezium, which is an open-source solution for Change Data Capture (and not just from MySQL!)

MySQLStreamer is a database change data capture and publish system. It’s responsible for capturing each individual database change, enveloping them into messages and publishing to Kafka.

In the bottom pane, you can execute any mysql statement on a barebones structure we’ve set up. Try creating a table and inserting into it to see it be sent (seen in the replication handler logs in the top right), and then received messages in the top left (seen in the kafka tailer’s logs). The received messages will probably look a little funky - this is because they’re avro-encoded.

We're still in the process of setting up this service as a stand-alone. There may be additional work required to run MySQL Streamer instances and integrate with other applications.
