Description
### Describe the enhancement requested
Currently (in a mature [PR](https://github.com/apache/arrow/pull/14682/)), the UDTF code does not respect the batch size provided in the context. See also [this post](https://github.com/apache/arrow/pull/14682/#discussion_r1057788434).
### Component(s)

Contributor guide
Research direction
Start by reviewing the UDTF code and mature PR #14682, including the linked discussion about batch size. Trace how the batch size is provided in the context and identify where user-defined tabular functions currently ignore it. Done means UDTFs respect the context-provided batch size.
