> Improve performance of serialization utils in ORC
> -------------------------------------------------
>
> Key: HIVE-7219
> URL: https://issues.apache.org/jira/browse/HIVE-7219
> Project: Hive
> Issue Type: Improvement
> Components: File Formats
> Affects Versions: 0.14.0
> Reporter: Prasanth J
> Assignee: Prasanth J
> Attachments: HIVE-7219.1.patch, HIVE-7219.2.patch, HIVE-7219.3.patch,
> HIVE-7219.4.patch, orc-read-perf-jmh-benchmark.png
>
>
> ORC uses serialization utils heavily for reading and writing data. The
> bitpacking and unpacking code in writeInts() and readInts() can be unrolled
> for better performance. Also double reader/writer performance can be improved
> by bulk reading/writing from/to byte array.
