> Key: FLINK-33266
> URL: https://issues.apache.org/jira/browse/FLINK-33266
> Project: Flink
> Issue Type: Sub-task
> Reporter: Dan Zou
> Assignee: Dan Zou
> Priority: Major
>
> In OLAP scenarios, running a single query typically cost hundreds of
> milliseconds or a few seconds, of which it takes about tens of milliseconds
> to parse, validate, optimize, and translate it to Flink transformations.
> Adding cache to cache the transformations corresponding to queries is
> meaningful for scenarios where certain queries are often executed repeatedly.
