### Search before asking - [X] I had searched in the [issues](https://github.com/apache/doris/issues?q=is%3Aissue) and found no similar issues. ### Description Java UDAF can do a lot of things. Unlike Java UDF, we always want a stateful computation. Now we could do it by the new Java UDAF function, but usually get a really BAD performance. That is because we can only get a row once a time through add API. If we could fetch rows in batch, we may use the concurrency to get faster. ### Use case _No response_ ### Related issues _No response_ ### Are you willing to submit 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.
