[jira] [Created] (ARROW-8979) [C++] Implement bitmap word reader
and writer
Yibo Cai created ARROW-8979:
-------------------------------
Summary: [C++] Implement bitmap word reader and writer
Key: ARROW-8979
URL: https://issues.apache.org/jira/browse/ARROW-8979
Project: Apache Arrow
Issue Type: Improvement
Components: C++
Reporter: Yibo Cai
Assignee: Yibo Cai
Below three Jira tasks optimize bitmap operations(logical, copy, compare, etc) unaligned case. They use word-by-word approach instead of bit-by-bit to improve performance.
There are some common code of read/write bitmap in words. It's better to implement word based bitmap reader and writer to wrap similar function and reduce code redundancy.
