# List Schemas

`GET /v1/datalake/schemas`

Retrieves schema information for all IDS (Intermediate Data Schema) in the organization.

**Performance Notice**: This endpoint may timeout with large datasets (500+ schemas). For better performance, use the targeted alternatives below.

**Recommended Alternatives**:
1. **List available IDS (if needed)**: `GET /v1/artifacts/ids`
2. **Get specific components**:
- Schema: `GET /v1/artifacts/ids/{namespace}/{slug}/{version}/files/schema`
- Mapping: `GET /v1/artifacts/ids/{namespace}/{slug}/{version}/files/mapping`
- Expected: `GET /v1/artifacts/ids/{namespace}/{slug}/{version}/files/expected`
- README: `GET /v1/artifacts/ids/{namespace}/{slug}/{version}/files/readme`

**When to use alternatives**: If you need specific schema details or are working with organizations that have many IDS definitions.
