Jark Wu commented on FLINK-12401:
---------------------------------
Incremental value is ACC? Is this issue going to support local-combine + global optimization for flatAggregate?

> As described in [Flip-29|https://cwiki.apache.org/confluence/pages/viewpage.action?pageId=97552739], there are two output modes for non-window streaming flatAggregate. One is emitting with full values, the other is emitting with incremental values. [FLINK-10977|https://issues.apache.org/jira/browse/FLINK-10977] supports the former one, this jira is going to support the latter one.
