 Description   

Investigate the POC of the new command "checkMetadataConsistency". This command will allow to spot possible metadata inconsistencies in a sharded cluster.

The goals of this proof of concept are:

  • Investigate how to expose the command to the clients: aggregation stage, typed command, etc.
  • Investigate the way of exposing different "level modes" of the command: cluster, database and collection.
  • Implement a proof of concept that looks for uuid mismatch inconsistencies at database level mode.
  • Do a jstests to validate the proof of concept.
