Hi, I use Spark 2.4.4
I've just noticed that the number of output rows metric of StateStoreSaveExec physical operator does not seem to be measured for Append output mode. In other words, whatever happens before or after StateStoreSaveExec operator the metric is always 0. It is measured for the other modes - Complete and Update. See https://github.com/apache/spark/blob/master/sql/core/src/main/scala/org/apache/spark/sql/execution/streaming/statefulOperators.scala#L329-L365 Is this intentional? Why?
