> In the current implementation, the BucketingSink rolls over a part file based on a _batchSize_ ([here|https://github.com/apache/flink/blob/release-1.4.0/flink-connectors/flink-connector-filesystem/src/main/java/org/apache/flink/streaming/connectors/fs/bucketing/BucketingSink.java#L459]).  Can we also support a roll over based on a constant time interval? This is not the same as the _inactiveBucketCheckInterval_ as this bucket is not truly inactive, it's still being written to but just has to be flushed every X minutes, where X is a user-specified time interval. 
> The change would involve tracking a _bucketCreationTime_ in the BucketState (much like the _lastWrittenToTime_) whenever a new part file is opened and would include a condition to check _currentProcessingTime_ - _bucketCreationTime_ > X in the _shouldRoll_ method.
