### Describe the enhancement requested `FixedSizeListVector#getObject` already performs this optimization; however, `ListVector`, `ListViewVector`, `LargeListVector`, and `LargeListViewVector` do not yet presize the result `JsonStringArrayList` requiring dynamic reallocations as elements are converted & added. This can become a scalability bottleneck when using these types. Example of `FixedSizeListVector` presizing: https://github.com/apache/arrow-java/blob/a6245ab87c782e2b873526acbd876cdf96d1f0ee/vector/src/main/java/org/apache/arrow/vector/complex/FixedSizeListVector.java#L476-L482 Example `ListVector` not presizing: https://github.com/apache/arrow-java/blob/a6245ab87c782e2b873526acbd876cdf96d1f0ee/vector/src/main/java/org/apache/arrow/vector/complex/ListVector.java#L718-L727 -- This is an automated message from the Apache Git Service.
