### Search before asking - [X] I had searched in the [feature](https://github.com/apache/incubator-seatunnel/issues?q=is%3Aissue+label%3A%22Feature%22) and found no similar feature requirement. ### Description 我尝试用spark从mysql的一张表中读数据，然后输出到控制台，发现卡住很久且内存溢出。 是因为spark会读全量数据吗？是否可以加query参数，主动过滤掉一些数据数据。 另外试了加transform，一样的情况，这样也做不到谓词下推吧？ ### Usage Scenario _No response_ ### Related issues _No response_ ### Are you willing to submit a PR? - [ ] 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.
