    Description

      Guidelines:

      Should include

      • Why is a filtering table needed? E.g. because orphans exist on a recipient during cloning and on a donor until active queries have ceased. This should make it clear that only data nodes have a filtering table (that is, mongos doesn't)

      Code references

      • Where is the filtering table for a particular query obtained?
      • Where is the filtering table for a particular query used to actually filter?
