# Quotas and limits in Yandex Data Processing

Yandex Data Processing has the following limits:

* [_Quotas_](https://console.yandex.cloud/cloud?section=quotas) are organizational constraints that can be changed by contacting technical support.
* _Limits_ are technical constraints of the Yandex Cloud architecture. You cannot change the limits.

If you need more resources, you can increase your quotas in one of the following ways:

* [Make a request to increase your quotas](https://console.yandex.cloud/cloud?section=quotas).
* Contact [support](https://center.yandex.cloud/support) and specify which quotas you want increased and by how much.

To have your request processed, you must have the `quota-manager.requestOperator` [role](../../iam/roles-reference.md#quota-manager-requestoperator) or higher, e.g., `editor` or `admin`.

You can manage your quotas with [Cloud Quota Manager](../../quota-manager/quickstart.md).

#### Quotas {#dataproc-quotas}

VMs that make up Yandex Data Processing clusters utilize your Yandex Compute Cloud cloud [quotas](https://console.yandex.cloud/cloud?section=quotas).
