PouchDB continuous replication without longpoll

Question

Is it possible to have continuous replication without using the longpoll feature. We are going to have around 300 clients connecting to a CouchDB server proxied via a Nodejs/Express server, and I feel this is going to affect normal requests.

I wanted to know if there were any other built-in options apart from manually triggering a periodic replication within a setInterval call.

This is how I am currently triggering the replication

db.sync(remoteDb, {
    live : true,
    retry : true,
});
