# Predefined datasets

Predefined datasets live in the [`default` dataspace](https://coralogix.com/docs/user-guides/data-layer/default-dataspace.md), next to the datasets you create. Coralogix defines each one's schema and entity type, but your own data fills it: the RUM events your SDK sends, the event markers you post, the AI telemetry your applications emit.

In **Dataset Management**, the **Managed by** column shows **Predefined** for these datasets. You can't delete or rename a predefined dataset or change its write access, but you can set its quota limit and access policy. Predefined datasets don't count toward your dataset limit. See [Dataset management](https://coralogix.com/docs/user-guides/data-layer/dataset-management.md#default-datasets).

## Queryable datasets[​](#queryable-datasets "Direct link to Queryable datasets")

| Dataset                                                                                                           | Entity type        | Description                                                              |
| ----------------------------------------------------------------------------------------------------------------- | ------------------ | ------------------------------------------------------------------------ |
| [`ai.evaluations`](https://coralogix.com/docs/user-guides/data-layer/default-dataspace/ai-evaluations.md)         | `aiEvaluations`    | GenAI evaluation results, including user feedback scores.                |
| [`ai.sessions.claude`](https://coralogix.com/docs/user-guides/data-layer/default-dataspace/ai-claude-sessions.md) | `aiSessionsClaude` | Claude Code session content: prompts, responses, tool calls, and errors. |
| [`ops.events`](https://coralogix.com/docs/user-guides/data-layer/default-dataspace/ops-events.md)                 | `opsEvents`        | Event markers, such as deployments, sent through the ops-events API.     |
| [`rum.events`](https://coralogix.com/docs/user-guides/data-layer/default-dataspace/rum-events.md)                 | `browserLogs/v2`   | Real User Monitoring events from your browser SDK.                       |

Query a predefined dataset by name, with or without the `default/` prefix:

```
source default/ops.events
```

Every predefined dataset in this table carries the standard log record envelope: engine metadata in `$m`, labels in `$l`, and the dataset-specific payload in `$d`. See [Entity types](https://coralogix.com/docs/user-guides/data-layer/entity-types.md) for how the envelope works.

## Storage datasets[​](#storage-datasets "Direct link to Storage datasets")

Some predefined datasets hold files that power Coralogix features rather than records you query. They appear in **Dataset Management** so you can see them and set their quota limit and access policy. Their entity types belong to the `binary` pillar, which stores files but doesn't structurally query them.

| Dataset             | What it stores                                      |
| ------------------- | --------------------------------------------------- |
| `sessionRecordings` | RUM session recordings.                             |
| `sessionSnapshots`  | Session snapshot data.                              |
| `mobileSnapshots`   | Mobile application snapshots.                       |
| `sourceMaps`        | Web application source maps.                        |
| `dsym`              | iOS debug information (dSYM files).                 |
| `proguard`          | Android debug information (ProGuard mapping files). |
