Hi, I have a query like `insert overwrite select`, which only has a resultTask but contains a huge resultSize 500+kb, i found it's caused by 8000+ accumulators which most are SQLMetric. The last stage is below:
It looks like there are CustomerShuffleReaderExec/BroadcastHashJoinExec/ProjectExec/SortExec, each sparkPlan only has a few SQLMetric, I'm confused why there are 8000+ SQLMetric. Anyone can help me? -- Penglei Shi
