Less than a month ago I wrote about Confluent’s KSQL, a sql engine on top of Kafka. It was still a developer preview and had some issues.
Yesterday Confluent launched version 4.1 of it’s platform that includes KSQL (see here for details and download). It seems that standalone KSQL is not available anymore and you must install it as part of the new Confluent platform.
I did not have the chance to actually test it in action, but I will try to do that soon and publish the result.
