… functions ## What is the purpose of the change This PR is meant to improve the performance of the built in json functions. The default `LRUCache` used in the JsonPath CacheProvider heavily use the lock which bring the bad performance. ## Brief change log - Create a new `JsonPathCache` and set it to the `CacheProvider` when load the class ## Verifying this change The functionality is covered by the existing tests. I have not written a performance test for it, If needed, I will add one. I manually test the case with the production job, which will have 2~4 times performance improvement. ## Does this pull request potentially affect one of the following parts: - Dependencies (does it add or upgrade a dependency): (no) - The public API, i.e., is any changed class annotated with `@Public(Evolving)`: (no) - The serializers: (no) - The runtime per-record code paths (performance sensitive): (no) - Anything that affects deployment or recovery: JobManager (and its components), Checkpointing, Kubernetes/Yarn, ZooKeeper: (no) - The S3 file system connector: (no) ## Documentation - Does this pull request introduce a new feature?
