I am trying to use a tailable cursor with stream. We are using mongoose and it works but when I launch my server with this code :

const listStream = ListsSub.find()
  .tailable({
    await_data: true,
    numberOfRetries: -1,
  })
  .stream();

my CPU is overheating.

Commentating the .stream() make the server runs great again.

I don't really know how to do without it. Is it something with my code ? Anyone experienced the same problem ?

EDIT :

  • mongoose : 4.11.3
  • mongodb : 3.4.6
  • node : 8.1.2
  • Server and mongodb on the same machine
mongoose node.js mongodb

I am using mongooseV5.9.2 and I needed to add below way to fix the issue

let options = { tailable: true, 
                awaitData: true, 
                numberOfRetries: -1, 
                tailableRetryInterval: 200
              };
    collection.find().cursor(options);
