Hello,
I’ve been trying to under stand “replica set” for a long time. We are using MongoDB 4.0.2. We are not replicating anything. We have 1 MongoDB instance running.
But, when reading about transactions. It says " * In version 4.0 , MongoDB supports multi-document transactions on replica sets."
- What does that mean?
- Do you have a single replica set as default?
- Do we need to create one?
Our system is now breaking and we need to solve this.
Thanks
What does that mean?
