Thanks for the great write up! I think this s very good starting point for a detailed discussion about features, syntax and semantics of streaming SQL. I'll comment on the document in the next days and describe Flink's current status, our approaches (or planned approaches) and ask a couple of ques

Hello Flink, Calcite, and Beam dev lists! Linked below is the second document I promised way back in April regarding a collaborative spec for streaming SQL in Beam/Calcite/Flink (& apologies for the delay; I thought I was nearly done a while back and then temporal joins expanded to something much
