Liya Fan commented on ARROW-10853:
----------------------------------

[~uwe] Thanks for reporting the problem. 
The ArrowVectorIterator should also be convenient to use (I think). Is there 
any special reason not to use it?

If there are too many Java internals, maybe we can consider simplify it to 
remove the internal stuffs?

> These helper functions are really useful when called from Python as they deal 
> with a lot of "internals" of Java that we don't want to handle from the 
> Python side. We rather would keep using these functions.
> Note that some of them are broken due to recent refactoring and only return 
> 1024 rows (the default iterator size) without the ability to change that.
