> [Java] Improving Arrow Vector Reading performance
> -------------------------------------------------
>
> Key: ARROW-5197
> URL: https://issues.apache.org/jira/browse/ARROW-5197
> Project: Apache Arrow
> Issue Type: Improvement
> Components: Java
> Reporter: Yurui Zhou
> Priority: Major
> Labels: pull-request-available
> Time Spent: 0.5h
> Remaining Estimate: 0h
>
> Currently the read interface of Java Arrow Vector is quite slow because the
> access operation has to go through validity bit check and boundary check
> before it can actually load the data. Such a safety check incurs unnecessary
> overhead in actually computation.
> The Arrow Vector and ArrowBuf should expose unsafe methods for advanced users
> to directly access underlying data without null check and boundary check.
