Hi Dev team, I'd like to start a discussion thread on Kafka Streams KIP-825: https://cwiki.apache.org/confluence/display/KAFKA/KIP-825%3A+introduce+a+new+API+to+control+when+aggregated+results+are+produced
This KIP is aimed to add new APIs to support outputting final aggregated results for windowed aggregations. I listed several options there and I'm looking forward to your feedback. Thanks, Hao
