### Describe the usage question you have. Please include as many useful details as possible. In arrow compute, `MetaFunction` means some "sepcial function", which "dispatch implementation to other impl. And the introduced pr is here: https://github.com/apache/arrow/commit/199d089e6343df1a1aa95f75b9e99e05a2702257 However, some function like "CAST" also has correspond kernel, and it just works like a normal function. Besides, why should it has a MetaFunction rather rathan a function with some "Match Any" Kernels? ### Component(s) C++ -- This is an automated message from the Apache Git Service.
