Thanks for writing this up @NoahKusaba. I kept chasing the same design in Comet and it was faster for a tiny number of partitions, but not practical for scale. If we buffer one batch in each output partition's coalescer - let's take a hypothetical 8MB per batch and 40,000 output partitions, we now have > 300 GB cached in memory. -- This is an automated message from the Apache Git Service.
