### Search before asking - [X] I had searched in the [DSIP](https://github.com/apache/dolphinscheduler/issues/14102) and found no similar DSIP. ### Motivation I am not clear why we set the hikari thread pool size, I don't find out any benchmark test result. Following https://github.com/brettwooldridge/HikariCP/wiki/About-Pool-Sizing, I hope to remove the configuration of hikari, the default setting is great enough. We shouldn't change the default setting unless we have benchmark evidence. https://github.com/apache/dolphinscheduler/blob/e66441a2c9ec38387b34f3712055af7308876efc/dolphinscheduler-api/src/main/resources/application.yaml#L52-L62 ### Design Detail Only keep the `pool name` and `connection-test-query` hikari: connection-test-query: select 1 pool-name: DolphinScheduler ### Compatibility, Deprecation, and Migration Plan Compatible with all version. ### Test Plan Test by e2e. ### 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.
