I think a bit of clarification is required. KCQL, kafka connect query language was jointly developed with Landoop when Confluent commissioned DataMountaineer to write the JDBC sink. The reason we added it was to simplify the configuration but it also enabled us to filter and support various options of the many data sources/sinks we have connectors for. Confluent removed the kcql from the sink and reverted to a flume style configuration we were trying to avoid. It's good to see Confluent plans to support their Ksql in Connect, following DataMountaineers lead. We hope this is optional. We can look at migrating if it supports all the options we need that KCQL provides.

Regarding Landoops proposal. This was not about KCQL but SQL on Streams, also named KSQL which is integrated with their new product Kafka Lenses. We'll look at Confluents SQL and see which one to go forward with, maybe both but we have happy customers using our version.

But congratulations on your KSQL very nice! We (Landoop and DM staff) have proved many ex colleagues in the Investment bank world wrong about Kafka and this cements our decisions to use it. Thanks.
