This document lists the quotas and limits that apply to Eventarc.
A quota restricts how much of a particular shared Google Cloud resource your Cloud project can use, including hardware, software, and network components.
Quotas are part of a system that does the following:
- Monitors your use or consumption of Google Cloud products and services.
- Restricts your consumption of those resources for reasons including ensuring fairness and reducing spikes in usage.
- Maintains configurations that automatically enforce prescribed restrictions.
- Provides a means to make or request changes to the quota.
When a quota is exceeded, in most cases, the system immediately blocks access to the relevant Google resource, and the task that you're trying to perform fails. In most cases, quotas apply to each Cloud project and are shared across all applications and IP addresses that use that Cloud project.
There are also limits on Eventarc resources. These limits are unrelated to the quota system. Limits cannot be changed unless otherwise stated.
|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.
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|
|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|
