Questions of gRPC and synchronization about Python Feature Server in feast #4489

Hi, I am newbie to feast. I plan to deploy feast Feature Server with Python(according to docs, Python Feature Server is supported) I have two questions about the feature server with python.

Q1. According to docs, Both Go Feature Server and Offline Feature Server is supported by gRPC protocol in addition to HTTP. But in Python Feature Server docs, Only HTTP is supported, right? gRPC protocol is not supported?

Q2. I heard that Feature Server(including Python, Go, Offline) is automatically synced registry.db file including metadata of FeatureView, FeatureService, other objects thorough background job. But without using Feature Server, if used by only python sdk, this automatic synchronization of registry.db file is not supported. Is this right?
