Sharding 2020-03-09, Sharding 2020-03-23, Sharding 2020-04-06
Description
The pipeline we'll use internally to discover inconsistent indexes uses output from $indexStats only present in v4.2.4 and later, and will use an aggregation expression $sort added in v4.4. We should verify that when run in a cluster with shards at mixed binary versions the pipeline does not incorrectly report inconsistent indexes and possibly do work to make the pipeline work better in such clusters.
