> FunctionExecutor currently handles dispatch to a kernel as well as allocation and invocation of the kernel. In some contexts (such as a filter expression bound to a specific schema) we only need to perform dispatch once, so repeatedly dispatching to kernel is redundant. Refactor to a KernelExecutor which is constructed from a pre-selected kernel.
