Yurui Zhou updated ARROW-5197:
------------------------------
Description:
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.
