I have been working with Google pubsub and was excited about their Push service that can post messages to subscribed endpoints/webhooks.

But their only method of throttling is to scale up and down base on failures. And it has been very unpredictable for me.

Even though my webhook started failing and timing out on requests, pubsub just kept hammering my servers until it brought it completely to it's knees. Logs on Google's end showed 1,500 failed attempts per second and 0.2 successes per second. It hammered at this rate for half an hour.

Seems like their Push option really needs some work.
