### Search before asking - [x] I searched in the [issues](https://github.com/apache/paimon/issues) and found nothing similar. ### Motivation Currently, `ArrowFormatWriter` is fixed to use `RootAllocator` without any memory settings, which does not facilitate fine-grained memory control. Additionally, there is no listener for allocation events. Therefore, I would like to support `ArrowFormatWriter` using an external `BufferAllocator`, enabling finer memory management and event monitoring in other frameworks. ### Solution I would like to provide a constructor for `ArrowFormatWriter` with a `BufferAllocator`. ### Anything else? _No response_ ### Are you willing to submit a PR? - [x] I'm willing to submit a PR! -- This is an automated message from the Apache Git Service.
