The following limits apply to Azure Event Grid system topics and custom topics, not event domains.
| Resource | Limit |
|---|---|
| Custom topics per Azure subscription | 100 |
| Event subscriptions per topic | 500 |
| Publish rate for a custom topic (ingress) | 5,000 events per second per topic |
| Event size | 1 MB. Operations are charged in 64 KB increments though. So, events over 64 KB will incur operations charges as though they were multiple events. For example, an event that is 130 KB would incur operations as though it were 3 separate events. |
| Topics per event domain | 100,000 |
| Event subscriptions per topic within a domain | 500 |
| Domain scope event subscriptions | 50 |
| Publish rate for an event domain (ingress) | 5,000 events per second |
| Event Domains per Azure Subscription | 100 |
| Private endpoint connections per topic or domain | 64 |
| IP Firewall rules per topic or domain | 16 |
