> Key: HUDI-1896
> URL: https://issues.apache.org/jira/browse/HUDI-1896
> Project: Apache Hudi
> Issue Type: New Feature
> Components: DeltaStreamer
> Reporter: Raymond Xu
> Priority: Critical
> Labels: pull-request-available
>
> As discussed in HUDI-1723, we need a better implementation for Cloud object storage like AWS S3 or GCS, leveraging on change notification.
> Also consider [https://docs.databricks.com/spark/latest/structured-streaming/sqs.html]
>
> We need to look into current *DFSSource classes and see if we can add a new `DFSPathSelector` implementation, that fetech new files on cloud storage after a given point in time. The timestamp based approach used by existing path selector, largely works, but has corner cases as mentioned in HUDI-1723
