I'm confused, is this just Structure of Arrays as a service for columnar data? It's not clear to me what this actually does.

It's not really a service at all, it is a in-memory data format intended to be shareable between processes. The project also includes libraries for C++, Java and Python.

This post explains the intention better than the project webpage:
