getDependentsoperation

getDependentsOperation is a data retrieval operation used to obtain the set of resources that depend on a given resource within a software system, data model, or asset registry. It is typically exposed as part of an API, SDK, or query interface and can be implemented as a function, method, or REST endpoint.

Purpose and scope: The operation supports impact analysis, change management, and dependency visualization by revealing dependents that might be affected when the resource changes or is retired. It helps teams understand downstream effects and plan mitigations.

Inputs and parameters: It usually requires a resource identifier and may include optional parameters such as pagination tokens, a maximum page size, filters by type or relationship, and a flag to include edge data or metadata. Some implementations allow narrowing results to specific environments, versions, or time windows.

Output and data model: The result is a collection of dependent entries, each with fields such as dependentResourceId, dependentResourceType, name, relationship (for example, uses, configuredBy, or consumes), and optional metadata like lastModified or impactScore. Results may be returned in a paginated form or as a streaming/cursor-based sequence.

Usage considerations: The operation is commonly asynchronous or provided via a paginated API to accommodate large graphs. Implementations may support caching, indexing on resource identifiers, and customizable projections to limit the amount of data returned per page.

Error handling: If the resource does not exist, a not-found error is returned. Access control violations may raise authorization errors. If no dependents exist, the operation returns an empty collection.
