Quotas and limits

This document lists the quotas and limits that apply to Translation Hub.

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 Translation Hub resources. These limits are unrelated to the quota system. Limits cannot be changed unless otherwise stated.


The following quotas apply to a project.

Quotas Value
Translation memory size 4* GB

* You can request a quota change through the Cloud Translation - Advanced API quotas page.
