    Description

      When verifying clusters for logical consistency as part of the verifier project, we can speed the process up by computing hashes server-side instead of transferring full documents over the network to the verifier process and computing the hashes there. Verification speed matters, as it's on the critical path for reducing downtime for MongoDB migrations.

      One potential option could be to introduce a new operator in the aggregation pipeline.
