> Key: FLINK-9609
> URL: https://issues.apache.org/jira/browse/FLINK-9609
> Project: Flink
> Issue Type: New Feature
> Components: filesystem-connector, Streaming Connectors
> Affects Versions: 1.5.0, 1.4.2
> Reporter: zhangminglei
> Assignee: zhangminglei
> Priority: Major
>
> Currently, BucketingSink only support {{notifyCheckpointComplete}}. But users
> want to do some extra work when a bucket is ready. It would be nice if we can
> support {{BucketReady}} mechanism for users or we can tell users when a
> bucket is ready for user use. For example, One bucket is created for every 5
> minutes, at the end of 5 minutes before creating the next bucket, the user
> might need to do something as the previous bucket ready, like sending the
> timestamp of the bucket ready time to a server or do some other stuff.
> Here, Bucket ready means all the part files name suffix under a bucket
> neither {{.pending}} nor {{.in-progress}}. Then we can think this bucket is
> ready for user use.
