Unbounded Source for MongoDB

[kennknowles]

The current MongoDB source is bounded, which means that we can't build streaming pipelines directly from MongoDB.
MongoDB publishes changes in each collection through the oplog. Would it be possible to create a connector that reads the oplog to create an unbounded source?

As an oplog is only available through replication, this creates that dependency. We would need to also consider whether a polling method (using the ObjectId) could be an appropriate fallback.

Thanks
