    Description

      In order to do this we would need to decide what should be done when a document cannot be found to update. The current behavior, of potentially creating a partial document, has some downsides when users make changes independent of replication, like during manual maintenance (or user/admin mistakes).

      We may also only want to make this change during normal replication, not when re-applying from a failed batch, during rollback, or in other cases where we may be working with repeated operations.
