------------------------------
Summary: Poor performance of the built in json_value function
Key: FLINK-28751
URL: https://issues.apache.org/jira/browse/FLINK-28751
Project: Flink
Issue Type: Improvement
Components: Table SQL / Runtime
Reporter: Aitozi
Attachments: image-2022-07-30-15-47-34-788.png
When I use the JSON_VALUE function, I found the performance is very poor. It's
mainly affected by the heavy lock operation in jsonpath inner LRUCache which is
also observed by other systems, eg:

So I purpose to use a different cache to replace the current one for better
performance.
