> Extend StreamingFileSink BulkFormats to support arbitrary roll policies
> -----------------------------------------------------------------------
>
> Key: FLINK-11499
> URL: https://issues.apache.org/jira/browse/FLINK-11499
> Project: Flink
> Issue Type: Improvement
> Components: Connectors / FileSystem
> Reporter: Seth Wiesman
> Priority: Major
> Labels: usability
> Fix For: 1.13.0
>
>
> 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.
