This project will add CLI options to the mongosync replicator. In particular, it will add a "commit" command to ensure the source and destination cluster are consistent with each other, and a command to control the direction of replication.

As the project is in early stages, this summary will be updated with more downstream impacts as the project progresses. Thanks!

Summary

Support reversing the direction of replication after a healthy cutover period

Motivation

While replicating data between two clusters, customers sometimes want the ability to swap roles between source and destination clusters - enabling them to switch their applications/business workflows back to the source cluster if they discover issues (data integrity, performance, other issues).
