### Describe the usage question you have. Please include as many useful details as possible. I'm curious about how substrait will play out and would like to play with the arrow integration. I've searched through [docs](https://arrow.apache.org/docs/cpp/acero/substrait.html#acero-substrait). Suppose I create a new acero extension that, say, computes a window function across the data, which doesn't exist today. At a glance, this could be [represented by Substrait primitives](https://substrait.io/expressions/window_functions/). Is there a well-formed guide (code works too) of how to register it with substrait? ### Component(s) C++ -- This is an automated message from the Apache Git Service.
