First of all, apologies for cross-posting. If you reply, please remove dev@flink and reply to dev@calcite only.
Calcite contributors, Fabian Hueske has sent an email to dev@flink [1] on their plans to add SQL and streaming SQL support to Flink using Calcite, and also included a design document [2]. We should be proud that they are putting their faith in us. I know that Calcite a sound platform for them to build on, but I also know that we will have to help them out, answering questions, adding features, and fixing bugs. So, please help them any way you can. The fact that we integrate with lots of projects (Drill, Hive, Phoenix, Kylin, Samza, Storm and now Flink) makes us a stronger platform for everyone. Do any of you want to get more involved in that effort? It would be great if one or two Calcite contributors were monitoring the Flink dev list, and were able to step in and help out. (I'm already maxed out with integrations: I subscribe to the Drill, Kylin and Samza dev lists, and have a daily stand up with Hive devs at Hortonworks.) Fabian and other Flink contributors, In future, feel free to CC: the Calcite dev list when you send emails about Calcite integration to the Flink list. I wouldn't consider it cross-posting. If there are interesting issues raised, folks on the Calcite side will subscribe to the Flink list (or watch the applicable Flink JIRA case). We want to help you out any way we can.
