Hi, I've read some docs (https://help.aliyun.com/document_detail/182011.html) stating Flink optimization technique using:
- partitionedJoin = 'true' - cache = 'ALL' - blink.partialAgg.enabled=true However I could not find any official doc references. Are these supported at all? Also "partitionedJoin" seemed to have the effect of shuffling input by joining key so they can fit into memory. I read this (https://flink.apache.org/news/2015/03/13/peeking-into-Apache-Flinks-Engine-Room.html) and believes this is already a default behavior of Flink. Is this optimization not needed even for huge input tables? Thanks, Dai
