Wes McKinney commented on ARROW-9843: ------------------------------------- I would suggest only implementing two versions, {{(data: Array, left: Array, right: Array)}} and {{(data: Array, left: Scalar, right: Scalar)}}. I added a missing "avoid" to the issue description. The idea is to compute BETWEEN as a loop of {{(left < data[i]) && (data[i] < right)}} instead of doing {{AND(GREATER(data, left), LESS(data, right))}} > [C++] Implement Between trinary kernel > -------------------------------------- > > Key: ARROW-9843 > URL: https://issues.apache.org/jira/browse/ARROW-9843 > Project: Apache Arrow > Issue Type: New Feature > Components: C++ > Reporter: Wes McKinney > Priority: Major > > A specialized {{between(arr, left_bound, right_bound)}} kernel would avoid > multiple scans and AND operation -- This message was sent by Atlassian Jira (v8.3.4#803005)
