| 16 | +# Service limits in Azure Machine Learning |
| 17 | + |
| 18 | +This section lists basic limits and throttling thresholds in Azure Machine Learning. |
| 19 | + |
| 20 | +> [!IMPORTANT] |
| 21 | +> Azure Machine Learning doesn't store or process your data outside of the region where you deploy. |

| 23 | +## Workspaces |
| 24 | + |
| 25 | +| Limit | Value | |
| 26 | +| --- | --- | |

| 49 | + |
| 50 | +## Metrics |
| 51 | +| Limit | Value | |
| 52 | +| --- | --- | |
| 53 | +| Metric names per run |50| |
| 54 | +| Metric rows per metric name |10 million| |
| 55 | +| Columns per metric row |15| |
| 56 | +| Metric column name length |255 characters | |
| 57 | +| Metric column value length |255 characters | |
| 58 | +| Metric rows per batch uploaded | 250 | |
| 59 | + |
| 60 | +> [!NOTE] |
| 61 | +> If you are hitting the limit of metric names per run because you are formatting variables into the metric name, consider instead to use a row metric where one column is the variable value and the second column is the metric value. |

| 70 | +## Limit increases |
| 71 | + |
| 72 | +Some limits can be increased for individual workspaces. To learn how to increase these limits, see ["Manage and increase quotas for resources"](how-to-manage-quotas.md) |
