rtadepalli opened a new pull request, #34424: URL: https://github.com/apache/arrow/pull/34424
### Rationale for this change This PR closes #15187. `FieldReader` is being allocated directly in the constructor today, and this PR changes it such that the initialization becomes lazy. Additionally, a new function `getTransferPair(Field, Allocator)` is introduced so that a new `Field` method is not constructed each time `getTransferPair` is called on the Vector. ### What changes are included in this PR? 1. Introduce a new `getTransferPair` method. 2. Make initializing `FieldReader` lazy. ### Are these changes tested? Yes, some tests have been added to verify these changes. ### Are there any user-facing changes? I am not 100% sure if there are any user facing changes. There should not be any breaking changes. -- This is an automated message from the Apache Git Service.
