# <a id="bitdrift.public.shared.workflows.v1.CardinalityOverflows"></a>CardinalityOverflows

| Field | Type | Description |
|---|---|---|
| total_overflows | <span class="proto-type proto-type-primitive">uint64</span> | The number of records that exceeded the total cardinality limit for the  action ID, including platform and app ID. |
| group_by_overflows | <span class="proto-type proto-type-primitive">uint64</span> | The number of records that exceeded only the group-by limit for the action  ID. This can include both client-side and server-side overflows. |
| query_group_by_collapsed | <span class="proto-type proto-type-primitive">bool</span> | If true, the query detected very high cardinality for a group-by request  and returned a collapsed result to avoid excessive memory use. Clients  should indicate that the group-by was collapsed and may offer example  cardinality details. |

#### Example
```json
{
  "group_by_overflows": 1,
  "query_group_by_collapsed": false,
  "total_overflows": 42
}
```
