Martijn Visser commented on FLINK-29346:
----------------------------------------
[~djkooks] I'm expecting that the filenames play a role in the exactly-once
guarantees of the FileSink, so I don't think it will be possible to change the
full file name yourself

I would expect that using the OutputFileConfig you should be able to make the
prefix and postfix depend on your input data

> Priority: Not a Priority

> Hello,
> I've made some research about file sink, but I couldn't find configuration
> about file naming (based on elements at stream).
> https://nightlies.apache.org/flink/flink-docs-release-1.13/docs/connectors/datastream/file_sink/
> Are there some reason about this? Because I need naming option of outputs,
> based on data in stream.
> Thanks.
