| Description |
|
Execution stat totalDataSizeGroupedBytesEstimate for $group stage reports the memory usage and not the total output bytes processed by $group pipeline. The stat is misleading in a sense that the actual data processed by $group stage will come out to be less when some data has been spilled to disk. In this ticket, we should fix this. |
