Analyzes cache effectiveness including: - Hit/miss rates - Latency comparison (cache vs full search) - Hourly cache performance trends **Use Cases:** - Evaluate cache effectiveness - Optimize cache TTL settings - Monitor cache performance - Identify cache warming opportunities **Example:** ```bash curl -X GET "https://api.mixpeek.com/v1/analytics/retrievers/ret_abc123/cache-performance?hours=168" \ -H "Authorization: Bearer YOUR_API_KEY" \ -H "X-Namespace: your-namespace" ``` ## OpenAPI ````yaml get /v1/analytics/retrievers/{retriever_id}/cache-performance 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}/cache-performance: get: tags: - Analytics - Analytics - Retrievers summary: Get Cache Performance description: >- Get cache performance metrics.
