Hi Vaibhav, I'm not sure if I understand your reply correctly. As a maintainer of parquet-cpp here, I think arrow-rs has set up a good example but we shouldn't blindly mirror everything from there. Our review process is pretty strict so it may take some time to finish. Now it is one of our top priorities and we're on the way so please have some patience.
