Event grid throughput limit

Question

I'm new to azure event grid concepts and currently doing research on event grid to implement in our project. Can any one tell about the throughput of event grid, how many events I can push per second and what is the egress of event grid per second, means count of output events per second from event grid.

Answer 1

Event Grid is build for large scale - millions of events per second in on throughput for both ingress and egress: https://docs.microsoft.com/en-us/azure/event-grid/overview#capabilities

There isn't a concept of a namespace in Event Grid, so you don't pre-provision a certain throughput capacity. It scales as you use it on a pay-per-operation basis.

Answer 2

I asked Microsoft about this topic and this was their response:

Nape: Publish rate limit is about 5000 events per second. This is the events you can publish to Event Grid. You can achieve rates higher than this if the service instance is not as loaded. Keep in mind EG is a multitenant system.

https://docs.microsoft.com/en-us/azure/iot-hub/iot-hub-event-grid-routing-comparison High: Capable of routing 10,000,000 events per second per region.

Above represents the capability of the entire service in dispatching events, per region.
