Wes McKinney created ARROW-9034: ----------------------------------- Summary: [C++] Implement binary (two bitmap) version of BitBlockCounter Key: ARROW-9034 URL: https://issues.apache.org/jira/browse/ARROW-9034 Project: Apache Arrow Issue Type: New Feature Components: C++ Reporter: Wes McKinney Assignee: Wes McKinney Fix For: 1.0.0
The current BitBlockCounter from ARROW-9029 is useful for unary operations. Some operations involve multiple bitmaps and so it's useful to be able to determine the block popcounts of the AND of the respective words in the bitmaps. So each returned block would contain the number of bits that are set in both bitmaps at the same locations -- This message was sent by Atlassian Jira (v8.3.4#803005)
