Description

Title: Implement ECDS for UDP listener filters

Description: Use-case: We'd like reload the configs independent of the listener. In our case, we're using the DNS filter and would like to be able to dynamically update the DNS entries without reloading the listeners.

Contributor guide

Research direction
Examine the existing ECDS implementation for TCP listener filters in Envoy and adapt it for UDP listener filters. Study the DNS filter to understand the requirements for dynamic updates.
