------------------------------------------
How do you mean? Can you successfully restore from a checkpoint? Or are you
restarting your application from scratch every time?
> using sink StreamingFileSink files are overwritten when resuming application
> causing data loss

> when part files are saved to s3 bucket (with bucket assigner) with simple
