Jark Wu commented on FLINK-31788:
---------------------------------
Hi [~hackergin], it seems the {{emitValueWithRetract}} was never introduced.
[FLIP-29|https://cwiki.apache.org/confluence/pages/viewpage.action?pageId=97552739]
proposed {{emitValueWithRetract}}, but it was implemented as
{{emitUpdateWithRetract}} in the first [PR|
https://github.com/apache/flink/pull/8550/files] (I don't know why the method
name was changed), and the {{emitUpdateWithRetract}} is still supported in the
latest version in the blink planner.
> Add back Support emitValueWithRetract for TableAggregateFunction
