Hi Lasse,
If the datastream job is used, you can try setting `OutputFileConfig`
for file sink, something like[1]:
```
OutputFileConfig config = OutputFileConfig
.builder()
.withPartPrefix("prefix")
.withPartSuffix(".ext")
.build();
FileSink<Tuple2<Integer, Integer>> sink = FileSink
.forRowFormat((new Path(outputPath), new SimpleStringEncoder<>("UTF-8"))
.withBucketAssigner(new KeyBucketAssigner())
.withRollingPolicy(OnCheckpointRollingPolicy.build())
.withOutputFileConfig(config)
.build();
```
