Related to a replicate operation, there was a [previous discussion in Zulip chat](https://ursalabs.zulipchat.com/#narrow/stream/271283-help.2Fc.2B.2B/topic/util.20to.20copy.20arrays.20to.20an.20existing.20buffer) of having a general replicate functionality where string repeat is a particular case. Arrow already has [`MakeArrayFromScalar`](https://github.com/apache/arrow/blob/master/cpp/src/arrow/array/util.cc#L742) and [`RepeatedArrayFactory`](https://github.com/apache/arrow/blob/master/cpp/src/arrow/array/util.cc#L493) which use [concatenate implementation](https://github.com/apache/arrow/blob/master/cpp/src/arrow/array/concatenate.cc) internally. Can this be used in this PR? These are specifically for Array types and in kernel transform method uses raw pointers. -- This is an automated message from the Apache Git Service.
