Thanks for creating this issue, @alamb! I think getting something like "Size-or-deadline" flush trigger into as many operators as possible (with values configured globally), can be the first step into better streaming semantics. You can avoid a global "streaming" flag by simply choosing how to flush batches, for example: - Batch system: size: 8k, deadline: disabled. - Streaming system: size: 1k, deadline: 100ms. Control-message propagation also would be a really cool building block: you could build high-level functionality like checkpointing, windowing, etc. -- This is an automated message from the Apache Git Service.
