-----------------------------------
Hi, [~maccamlc]
# Currently, there is no public API that could let you register your own
listener.
# Do you need to be notified every time when a file is committed? or to only
be notified when a bucket is updated?
thanks.
> 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
> 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?
