> Currently when using the StreamingFilleSink Bulk-encoding formats can only be combined with the `OnCheckpointRollingPolicy`, which rolls the in-progress part file on every checkpoint.
> However, many bulk formats such as parquet are most efficient when written as large files; this is not possible when frequent checkpointing is enabled. Currently the only work-around is to have long checkpoint intervals which is not ideal.
>  
> The StreamingFileSink should be enhanced to support arbitrary roll policy's so users may write large bulk files while retaining frequent checkpoints.
