Overview
A query interface for retrieving and filtering previously traced call records from the backend.
Description
Call Retrieval provides a programmatic interface to query traced calls stored in the backend. It supports filtering by operation name, parent ID, trace ID, and custom expressions; sorting; pagination; and field projection for performance optimization.
Usage
Use this principle when you need to programmatically analyze traced calls — for example, to build custom dashboards, compare model behavior across runs, or export trace data for analysis.
Theoretical Basis
Call retrieval follows the query-filter-paginate pattern:
- Filtering: Narrow results by structured criteria (op names, parent IDs, trace IDs, input refs).
- Querying: Apply advanced Mongo-like expressions for complex conditions.
- Sorting: Order results by any field (e.g., started_at desc).
- Pagination: Use limit/offset for bounded result sets.
- Projection: Select specific columns to reduce response size and improve performance.
