Hi! Thanks for all this. and yes I was indeed talking about SQL/Table API so I will keep track of these tickets! BTW, What is non-windowed Join? I thought stream-stream-joins by default is a stateful operation so it has to be within some time window right? Also does the output of stream-stream joins emit every time so we can see the state of the join at any given time or only when the watermark elapses and join result fully materializes?
On a side note, Full outer join seems to be the most useful for my use case. so the moment its available in master I can start playing and testing it!
