How to gracefully retention one RSS server?

[hbpeng0115]

We have several RSS servers, if we want to gracefully retention one RSS server which need to be transparent to user and user's shuffle replica is 1. Do we have any solution, like only output data but not write new data?

This is a good feature, but not implemented in RSS yet. You could contribute for this.

Got it, do you have more detailed introduction doc on RSS server, I want to know the design and code architecture of RSS.

There is high level design doc in this repo (https://github.com/uber/RemoteShuffleService/blob/master/docs/server-high-level-design.md) which describes the concepts of how RSS works. I do not work in Uber any more, thus not actively working in this project right now.
