rename parameter to `bucket.creationTime`? At this point, nothing has been
written to the file. Actually, the file has not even been created yet.
> Enhance BucketingSink to also flush data by time interval

> Key: FLINK-9138

> Project: Flink
> Issue Type: Improvement
> Components: filesystem-connector
> Affects Versions: 1.4.2
> Reporter: Narayanan Arunachalam
> Priority: Major
>
> BucketingSink now supports flushing data to the file system by size limit and
> by period of inactivity. It will be useful to also flush data by a specified
> time period. This way, the data will be written out when write throughput is
> low but there is no significant time period gaps between the writes. This
> reduces ETA for the data in the file system and should help move the
> checkpoints faster as well.
