### Description of PR I recently came across a NN log where about 800k setRep calls were made, setting the replication from 3 to 3 - ie leaving it unchanged. Obviously the application should be fixed, but we could have an optimisation for this. When the replication is unchanged in a case like this, we log an edit record, an audit log, and perform some quota checks etc. I believe we should still log an audit in these sort of cases, but we can skip all the checks and avoid writing an edit. ### How was this patch tested? Added a new test and validated the code paths were correct around writing and syncing edits or not with some log messages I then removed. -- This is an automated message from the Apache Git Service.
