Micah Kornfield commented on ARROW-5778:
----------------------------------------
lets make sure to benchmark/check assembly to ensure no performance regression
> [Java] Extract the logic for vector data copying to the super classes
> ---------------------------------------------------------------------
>
> Key: ARROW-5778
> URL: https://issues.apache.org/jira/browse/ARROW-5778
> Project: Apache Arrow
> Issue Type: Improvement
> Components: Java
> Reporter: Liya Fan
> Assignee: Liya Fan
> Priority: Major
>
> Currently, each vector has its own {{copyFrom}} method. The implementations
> for fixed-width vectors are similar, whereas the implementations for the
> variable-width vectors are similar.
> This issue extract such implementations to the base classes, with the
> following benefits:
> 1. Less code makes it easier to maintain
> 2. Move the method to the base class makes the method more convenient to use.
