> Project: Flink
> Issue Type: Improvement

> Selectors is often used in the transform module to determine whether a table
> meets the matching rules. However, Selectors#isMatch is a relatively slow
> method that uses regularization to match table names.
> If we can add a cache to cache all matched tables, there will be better
> performance optimization.
