[jira] [Commented] (ARROW-8762) [C++][Gandiva] Replace Gandiva's BitmapAnd with common implementation

    [ https://issues.apache.org/jira/browse/ARROW-8762?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17107660#comment-17107660 ] 

Wes McKinney commented on ARROW-8762:
-------------------------------------

This may not be possible yet without some benchmarking since Gandiva's BitmapAnd processes 8 bytes at a time instead of one byte at a time.
