----------------------------------
Assignee: Jean-Baptiste Onofré (was: Davor Bonaci)
> Unbounded Source for MongoDB
> ----------------------------
>
> Key: BEAM-2639
> URL: https://issues.apache.org/jira/browse/BEAM-2639
> Project: Beam
> Issue Type: Bug
> Components: sdk-java-extensions
> Affects Versions: 2.0.0
> Reporter: nevi_me
> Assignee: Jean-Baptiste Onofré
> Priority: Minor
>
> 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
