Quotas are part of a system that does the following:\n\n- Monitors your use or consumption of Google Cloud products and services.\n- Restricts your consumption of those resources for reasons including ensuring fairness and reducing spikes in usage.\n- Maintains configurations that automatically enforce prescribed restrictions.\n- Provides a means to make or request changes to the quota.\n\nWhen a quota is exceeded, in most cases, the system immediately blocks access to\nthe relevant Google resource, and the task that you're trying to perform fails.\nIn most cases, quotas apply to each Google Cloud project and are shared across\nall applications and IP addresses that use that Google Cloud project.\n\nTo increase or decrease select quotas, use the Google Cloud console. For more\ninformation, see\n[Request a quota adjustment](/docs/quotas/view-manage#requesting_higher_quota).\n\nThere are also **limits** on resources. These limits are unrelated to the quota\nsystem. Limits cannot be changed unless otherwise stated.\n\nBy default, quotas and limits apply on a per-project basis.\n\nFor more information about data lineage quotas, see\n[Quotas for Data Lineage API requests](/dataplex/docs/quotas#lineage-quotas).\n\nQuotas\n------\n\nTo calculate an organization's QPM (queries per minute),\nData Catalog adds together the QPM of projects in the\norganization.\n\nData Catalog uses QPM quotas to prevent service overload\nrather than control request workload distribution among projects. Therefore,\nboth project and organization have the same default QPM quotas. In other words,\nif an organization has multiple projects and the request workload of one of them\napproaches the default organization (and the same project) quota, this project\nmight impact the potential workload of the other projects in the organization.\n\nTo adjust organization and project quotas separately, see\n[Request a quota adjustment](/docs/quotas/view-manage#requesting_higher_quota).\n\n| **Note:** Listed quotas represent upper QPM bounds, and are not guaranteed.\n\nFor more information about BigQuery quotas, see [BigQuery quotas \\& limits](/bigquery/quotas).\n\nLimits\n------\n\nThe Data Catalog API enforces limits for entries, tags, and business metadata.\n\n### Entry limits\n\n### Tag limits\n\n### Business metadata limits"]]
