Assignee: Yun Gao
> Add Bucket lifecycle listener to support acquiring bucket state

> Key: FLINK-17590
> URL: https://issues.apache.org/jira/browse/FLINK-17590
> Project: Flink
> Issue Type: Sub-task
> Components: Connectors / FileSystem
> Reporter: Yun Gao
> Assignee: Yun Gao
> Priority: Major
> Fix For: 1.11.0

>
> Hive sink will reuse the Buckets class of StreamingFileSink, which
> encapsulate most of the logic of StreamingFileSink. Hive sink requires to
> writing one-piece of meta-info into Hive meta store after a partition (namely
> Bucket in StreamingFileSink) has been terminated. Currently the termination
> is judged by event-time/processing time
> ([FLIP-115|[https://cwiki.apache.org/confluence/display/FLINK/FLIP-115%3A+Filesystem+connector+in+Table]]).
>
> To support the requirement of the Hive Sink, we would add listener for
> acquiring the event bucket creation and getting inactive. A bucket get
> inactive if all the previous records have been committed. Then Hive Sink
> could safely writing meta-info if the time has exceeded the bucket's boundary
> and it has been inactive.
