> Key: FLINK-11729
> URL: https://issues.apache.org/jira/browse/FLINK-11729
> Project: Flink
> Issue Type: Improvement
> Components: Runtime / State Backends
> Reporter: Yu Li
> Assignee: Yu Li
> Priority: Major
> Fix For: 1.8.0
>
>
> In FLINK-10043 we have introduced builder pattern for
> {{RocksDBKeyedStateBackend}} and moved all necessary initialization of the
> backend into the builder, out of which the most important part is the
> {{restore}} operation. None of the backends could actually supply service
> before the restore operation is done, so it's native to make restore part of
> the _building phase_.
> In this JIRA we propose to make all backends follow the builder pattern. More
> specifically, create builders for {{HeapKeyedStateBackend}} and
> {{DefaultOperatorStateBackend}} and move their {{restore}} operations into
> the builders. Will create sub-tasks for each of them.
