[jira] [Commented] (ARROW-9006) [C++] Use Cast kernels to implement Scalar::Parse and Scalar::CastTo

    [ https://issues.apache.org/jira/browse/ARROW-9006?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17148572#comment-17148572 ] 

Krisztian Szucs commented on ARROW-9006:
----------------------------------------

We'll need to add support for copying scalars and casting temporal scalars before we can switch to the compute implementation.

> We should not maintain distinct (and possibly differently behaving) implementations of elementwise array casting and scalar casting. The new kernels framework provides for relatively easily generating kernels that can process arrays or scalars.
