Yandex Cloud services can be subject to quotas and limits:
- Quotas are organizational restrictions that can be changed by technical support on request.
- Limits are technical limitations due to Yandex Cloud architectural features. The limits cannot be changed.
When designing your infrastructure in Yandex Cloud, plan for the maximum limits that Yandex Cloud can provide you with. Quotas are restrictions that can potentially be increased up to their limit.
Why quotas are needed
Quotas serve as a soft restriction for requesting resources and enable Yandex Cloud to guarantee service stability, because new users can't take up too many resources for testing purposes. If you're willing to use more resources, you can increase them in the following ways:
- Generate a request for a quota increase.
- Contact support and tell us which quotas you need to increase and by how much.
Default quotas and limits for Yandex Cloud services
Quotas are listed with default values that match the quotas of the trial period.

4 To achieve maximum IOPS, we recommend performing read and write operations whose size is close to that of the disk block (4 KB by default).
5 To achieve the maximum possible bandwidth, we recommend performing 4 MB reads and writes.

Chart data limits
Each chart has a limit on the amount of data it can display.
Every time DataLens tries to visualize a chart, it makes a request to a dataset.
If a metric (such as the number of rows returned) is over limit, DataLens will not display the chart.
You can modify the amount of data returned. Modify the query parameters to filter out some rows, for example.
