Creating a replica of redis session store

When used as a session store in an expressjs/nodejs app as such:

var express = require("express");
var session = require('express-session');
var redis = require("redis");
var redisStore = require('connect-redis')(session);
var redisClient = redis.createClient();
// more dependencies are loaded here...

app.use(session({
secret: 'mysecret',
// create new redis store.
store: new redisStore({ host: 'localhost', port: 6379, client: redisClient }),
saveUninitialized: false,
resave: false
}));

is there a way to create a replica of redisStore with the session data as the initial store. Are there any PubSub events when ever a new session is added, or removed from the store? I was thinking of using pubsub, and having two separate redis session stores, where one publishes to the other. Is this possible, is it the best solution?

Begin with the express-session configuration shown in the report, then inspect connect-redis and Redis Pub/Sub documentation to determine whether session creation/removal events and initial-store replication are supported. Done requires a documented, agreed approach or a narrowly scoped implementation target; the issue currently names no files or tests.
