The Get Resource Instances endpoint supports several query parameters that can help narrow down results and potentially improve performance (1) : •

tenant

- Filter by tenant key or id •

resource

- Filter by resource key or id •

search

- Filter by resource instance key or id (supports multi-value) •

page

and

per_page

- Control pagination (max 100 per page) •

detailed

- If true, returns relationships of the resource instance •

include_total_count

- Include total count in response (will make the request slower) To help investigate the timeout issues, could you provide: 1. Which Workspace / Project / Env you are using 2. What calls are you performing (as SDK code or CURL) 3. Which PDP version you are running 4. Relevant logs from your PDP Additionally, it would be helpful to know: • How many resource instances you're trying to retrieve • Whether you're using any of the filtering parameters mentioned above • If you're setting

include_total_count=true

(which can slow down requests) If you're retrieving a large number of instances, consider using pagination with smaller

per_page

values or applying filters to reduce the dataset size .
