qingyang.chen, re-opening for 3.1.8 as I think there is some additional work left to do. If you compare the stats reported in "executionStats" mode for IXSCAN and DISTINCT_SCAN, you'll see that there is much less information in the distinct case. We need to update Explain::statsToBSON() to add the missing information for DISTINCT_SCAN. |
