Temp collection of mapReduce (such as below) are replicated nevertheless it's useless moreover so frequently.
- "<db name>.tmp.mr.<collection name>_1"
- "<db name>.tmp.mr.<collection name>_1_inc"
This issue causes big transaction so performance is quite deteriorated.
The primary node will hangup in many case.
We can confirm this replication by looking local.rs.oplog.
