CardinalityOverflows¶
| Field | Type | Description |
|---|---|---|
| total_overflows | uint64 | Overflowed the total limit for the action ID, including platform and app ID. |
| group_by_overflows | uint64 | Overflowed only the group by limit for the action ID. This can include both client overflows as well as server overflows. |
| query_group_by_collapsed | bool | If this is true, during query time the query engine detected very large cardinality during a group by query. Even with ingestion limits, it's still possible if the data is problematic and we are querying over a very large window. In order to avoid OOM during TopK processing, the query engine will fall back to a collapsed group by query which will return a single time series. The FE should display an indication that this happened as well as the ability to view example cardinality. |
