             Summary: Extend StreamingFileSink BulkFormats to support arbitrary roll policy's
                 Key: FLINK-11499
                 URL: https://issues.apache.org/jira/browse/FLINK-11499
             Project: Flink
          Issue Type: Improvement
            Reporter: Seth Wiesman


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.
