> Use the mailboxExecutor for operator in Async state processing
> --------------------------------------------------------------
>
> Key: FLINK-37642
> URL: https://issues.apache.org/jira/browse/FLINK-37642
> Project: Flink
> Issue Type: Improvement
> Components: Runtime / Async State Processing
> Affects Versions: 2.0.0
> Reporter: Zakelly Lan
> Assignee: Yanfei Lei
> Priority: Major
> Labels: pull-request-available
> Fix For: 2.1.0
>
>
> Currently, the operators of async state processing use the main mailbox
> executor for callback execution, which has low priority. It's better to use
> the one for `YieldingOperator`, as:
> {code:java}
> MailboxExecutor mailboxExecutor =
> containingTask
> .getMailboxExecutorFactory()
> .createExecutor(configuration.getChainIndex());
> {code}
> It has higher priority, which could help us do efficient `yield()`.
