-----------------------------------------
Hi [~maguowei]
Thanks for the response.
My use case is that I need to know every time that a file has been committed.
Then I can get the object key for S3 and publish a message elsewhere that other
services can act upon to download and use the files, as soon as possible.
I have found a way using reflection to get down to the
pendingPartsPerCheckpoint.headMap(checkpointId, true) map before
notifyCheckpointComplete is called.
Regards,
Matt
> Listener for when Files are committed in StreamingFileSink

> Key: FLINK-17900
> URL: https://issues.apache.org/jira/browse/FLINK-17900
> Project: Flink
> Issue Type: Improvement
> Components: Connectors / FileSystem
> Affects Versions: 1.10.0
> Reporter: Matthew McMahon
> Priority: Major
>
> I have a scenario where once a file has been committed to S3 using the
> StreamingFileSink (I am using Java), that I should notify some downstream
> services.
> The idea is to produce a message on a Kafka topic for the files as they are
> finalized.
> I am currently looking into how this might be possible, and considering using
> reflection and/or checking the S3 bucket before/after the checkpoint is
> committed.
> Still trying to find a suitable way.
> However I was thinking it would be great if possible to register a listener
> that can be fired when StreamingFileSink commits a file.
> Does something like this exist, that I'm not aware of (new to flink) or could
> it be added?
