This document lists the quotas and system limits that apply to Eventarc. Quotas specify the amount of a countable, shared resource that you can use, and they are defined by Google Cloud services such as Eventarc. System limits are fixed values that cannot be changed.
Google Cloud uses quotas to help ensure fairness and reduce spikes in resource use and availability. A quota restricts how much of a Google Cloud resource your Google Cloud project can use. Quotas apply to a range of resource types, including hardware, software, and network components. For example, quotas can restrict the number of API calls to a service, the number of load balancers used concurrently by your project, or the number of projects that you can create. Quotas protect the community of Google Cloud users by preventing the overloading of services. Quotas also help you to manage your own Google Cloud resources.
The Cloud Quotas system does the following:
- Monitors your consumption of Google Cloud products and services
- Restricts your consumption of those resources
- Provides a way to request changes to the quota value
In most cases, when you attempt to consume more of a resource than its quota allows, the system blocks access to the resource, and the task that you're trying to perform fails.
Quotas generally apply at the Google Cloud project level. Your use of a resource in one project doesn't affect your available quota in another project. Within a Google Cloud project, quotas are shared across all applications and IP addresses.
There are also system limits on Eventarc resources. System limits can't be changed.
Quotas
| Quota | Description | Value | Can be increased | Scope |
|---|---|---|---|---|
| Trigger read requests | The number of Eventarc Trigger API reads per minute per project | 6000 | Yes | Per project |
| Trigger write requests | The number of Eventarc Trigger API writes per minute per project | 600 | Yes. The global location has a write limit of 10 QPS. | Per project |
Request an increase in quota
If your project needs more of a particular resource than your quotas allow, you can request an increase to most quotas in the Google Cloud console. For more information, see About quota increase requests.
Limits
The number of Eventarc resources is limited for a given project. There is no direct limit on the size of the Eventarc API request.
| Resource | Description | Limit | Can be increased | Scope |
|---|---|---|---|---|
| Trigger | Maximum number of triggers | 500 | No | Per location per project |
| Trigger | Maximum number of triggers for internal HTTP endpoints | 100 | No | Per project |
| Event | Event size | 512 KB | No | N/A |
| Published events (third-party and custom events) | The number of third-party and custom events that can be published per project across all channels | 300 | No. To request an exception, contact support. | Per project |
