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. https://issues.apache.org/jira/browse/ARROW-8553 https://issues.apache.org/jira/browse/ARROW-8843 https://issues.apache.org/jira/browse/ARROW-8844 -- This message was sent by Atlassian Jira (v8.3.4#803005)
