i want to know why mongo only support muti-doc txn in replica and shard, sometimes we want to test transaction but mush deploy replica, it’s troublesome

Hi @timer_izaya,

Multi-document transactions rely on the replication oplog which is not present on a standalone mongod deployment.

However, you can deploy a single node replica set for test purposes.
