> Separately, we do a fair amount with aggregation and another pain point I've come across is the lack of a way to peek at aggregate state or evaluate only a subset of a group. Supporting this would make incremental emission from time-windowed aggregation operators more efficient. I filed two related issues with concrete API proposals: - https://github.com/apache/datafusion/issues/24602 - https://github.com/apache/datafusion/issues/24603 The motivating use case is stateful stream processing, but both APIs are general and do not necessarily tie DataFusion to any sort of stream processing model. -- This is an automated message from the Apache Git Service.
