morningman opened a new issue #6584: URL: https://github.com/apache/incubator-doris/issues/6584
### Search before asking - [X] I had searched in the [issues](https://github.com/apache/incubator-doris/issues?q=is%3Aissue) and found no similar issues. ### Version trunk de66312 ### What's Wrong? ``` select count(1) from xxx where f1 rlike 'xxx'; select count(1) from xxx where lower(f1) rlike 'xxx'; ``` The second query results in Memory exceed limit, but the first one won't. ### What You Expected? count(1) shouldn't consume that much memory. ### How to Reproduce? Execute a query with function `lower()` ### Anything Else? This is because we do not release the memory temporarily used by `lower()` function. ### Are you willing to submit PR? - [X] Yes I am willing to submit a PR! ### Code of Conduct - [X] I agree to follow this project's [Code of Conduct](https://www.apache.org/foundation/policies/conduct) -- This is an automated message from the Apache Git Service.
