> --------------------------------------------------
>
> Key: ARROW-7072
> URL: https://issues.apache.org/jira/browse/ARROW-7072
> Project: Apache Arrow
> Issue Type: New Feature
> Components: Java
> Reporter: Liya Fan
> Assignee: Liya Fan
> Priority: Major

> For scenarios when we need to concate vectors (like the scenario in ARROW-7048, and delta dictionary), we need a way to concat validity bits.
> Currently, we have bit level API to read/write individual validity bit. However, it is not efficient , and we need a way to copy more bits at a time.
