> 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
