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)
