Wes McKinney resolved ARROW-9034. --------------------------------- Resolution: Fixed Issue resolved by pull request 7356 [https://github.com/apache/arrow/pull/7356] > [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 > Priority: Major > Labels: pull-request-available > Fix For: 1.0.0 > > Time Spent: 1h 40m > Remaining Estimate: 0h > > 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)
