| Scenario | Recommended approach | |
|---|---|---|
| Fetch fields for a known record ID | getRecord (UI API) | |
| Display a standard related list | getRelatedListRecords (UI API) | |
| Fetch multiple related lists from one parent | getRelatedListRecordsBatch (UI API) | |
| Filter records by criteria (no known ID) | GraphQL wire adapter | |
| Join data across multiple objects in one request | GraphQL wire adapter | |
| Aggregations (COUNT / SUM / etc.) | GraphQL wire adapter | |
| Cursor-based pagination for large lists | GraphQL wire adapter | |
| Simple create / update / delete (no business logic) | executeMutation (GraphQL) or uiRecordApi | |
| DML with validation or triggers you need to control | Apex |
