Description

In case there are hundreds of routes under each virtual host within same route configuration, would it be better to use RDS + VHDS than just RDS? Or the difference can be ignored? If not, should VHDS + static route config be supported?

Contributor guide

Research direction
Investigate the current implementation of VHDS and static route config in Envoy. Analyze the trade offs between using RDS alone vs RDS+VHDS for hundreds of routes. Assess if adding VHDS support for static routes is beneficial and feasible, and propose a design if so.
