[jira] [Created] (ARROW-5197) [Java] Improving Arrow Vector Reading performance

Yurui Zhou created ARROW-5197:
---------------------------------

             Summary: [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
            Assignee: Yurui Zhou


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. 

The Arrow Vector and ArrowBuf should expose unsafe methods for advanced users to directly access underlying data without null check and boundary check.
