node.js - Heroku 2 dynos for nodejs app with node-cron module. How it will work? -

i have nodejs app running on 2 dynos. have cron module run syncing external mysql db mongodb. question is. running on 2 dynos, cron jobs run twice, 1 time each app, cron jobs within nodejs app?

heroku dynos not have cron available. dynos stateless , know nil of other dynos, if cron available, each dyno run own , you'd have duplication.

if need cron-like functionality, should utilize heroku scheduler:

node.js heroku cron
