Combine this with Debezium[1] and you get real-time SQL queries on your MySQL/PostgreSQL/MongoDB database!

RethinkDB, as far as I understand, does the same thing - their changefeed mechanism would consume the DB log and run the queries against the log.

Yes, exactly. We plan to add support for various Kafka connectors to KSQL so you can ingest/export streams from external systems, like database, and then do stream processing all using KSQL queries.

The purpose is to bring Streaming ETL and Stream Processing together to make the user's life easy.
