Rok Mihevc updated ARROW-4567: ------------------------------ External issue URL: https://github.com/apache/arrow/issues/21113 > [C++] Convert Scalar values to Array values with length 1 > --------------------------------------------------------- > > Key: ARROW-4567 > URL: https://issues.apache.org/jira/browse/ARROW-4567 > Project: Apache Arrow > Issue Type: New Feature > Components: C++ > Reporter: Wes McKinney > Priority: Major > > A common approach to performing operations on both scalar and array values is > to treat a Scalar as an array of length 1. For example, we cannot currently > use our Cast kernels to cast a Scalar. It would be senseless to create > separate kernel implementations specialized for a single value, and much > easier to promote a scalar to an Array, execute the kernel, then unbox the > result back into a Scalar -- This message was sent by Atlassian Jira (v8.20.10#820010)
