Quotas and limits in Visualization
The following limitations apply to the DoubleCloud Visualization service:
- Limits are technical conditions due to DoubleCloud architectural features. You can't change the limits.
Limits
| Limit description | Value |
|---|---|
| Maximum number of rows of persisted data per dataset | 100 000 000 |
| Maximum number of fields per dataset | 1 200 |
| Maximum number of tables in one dataset | 32 |
Warning
If you exceed any of the above limits, you won't be able to save your dataset. You also can't add to your dataset a data source that tops the above limits.
Data limits for charts
Every chart has a limit for the number of data lines it can display.
To display a chart, the service queries the selected dataset. If the number of lines in the return query is higher than the limit, Visualization won't display the chart. In this case, adjust the number of lines in the return query. For example, you can apply filtration to your dataset or select a different chart type.
