Analyzes individual stage performance to identify bottlenecks: - Stage execution times - Document flow (in/out) - Stage-level latency distribution **Use Cases:** - Identify slow stages in retrieval pipeline - Optimize stage ordering - Debug pipeline bottlenecks - Understand document reduction rates **Example:** ```bash curl -X GET "https://api.mixpeek.com/v1/analytics/retrievers/ret_abc123/stages?hours=24" \ -H "Authorization: Bearer YOUR_API_KEY" \ -H "X-Namespace: your-namespace" ``` ## OpenAPI ````yaml get /v1/analytics/retrievers/{retriever_id}/stages openapi: 3.1.0 info: title: Mixpeek API description: >- This is the Mixpeek API, providing access to various endpoints for data processing and retrieval. termsOfService: https://mixpeek.com/terms contact: name: Mixpeek Support url: https://mixpeek.com/contact email: info@mixpeek.com version: '0.82' servers: - url: https://api.mixpeek.com description: Production security: [] paths: /v1/analytics/retrievers/{retriever_id}/stages: get: tags: - Analytics - Analytics - Retrievers summary: Get Stage Breakdown description: >- Get stage-level performance breakdown.
