| Description |
|
Currently, adding the repl metadata to any command requires access into the topology coordinator, which might be a significant performance penalty. Need to investigate moving the data it needs into the replCoord, or splitting up the data so that you need to request the more expensive data items explicitly (such as the current primary id). |
