Li Jin created ARROW-3495:
-----------------------------

             Summary: Optimize bit operations performance
                 Key: ARROW-3495
                 URL: https://issues.apache.org/jira/browse/ARROW-3495
             Project: Apache Arrow
          Issue Type: Task
          Components: Java
    Affects Versions: 0.11.0
            Reporter: Li Jin


>From [~atrivedi]'s benchmark finding:

2) Materialize values from Validity and Value direct buffers instead of
calling getInt() function on the IntVector. This is implemented as a new
Unsafe reader type (
[https://github.com/animeshtrivedi/benchmarking-arrow/blob/master/src/main/java/com/github/animeshtrivedi/benchmark/ArrowReaderUnsafe.java#L31]
)

3) Optimize bitmap operation to check if a bit is set or not (
[https://github.com/animeshtrivedi/benchmarking-arrow/blob/master/src/main/java/com/github/animeshtrivedi/benchmark/ArrowReaderUnsafe.java#L23]
)
