July 2025 - mlrun/mlrun: Delivered Model Monitoring improvements with Function Summaries API, batch processing, and streaming metrics; strengthened observability and scalability to drive faster detection and resolution of model issues. Key milestones include core API and schemas for function summaries, data-source and stream metrics enrichment (V3IO, Kafka), time-series connector updates to count processed endpoints and latest metrics, and batch event processing for scalable monitoring. Added committed offset and lag statistics to function-summaries API for V3IO and Kafka, improving troubleshooting for streaming sources. Fixed test_app to test only supported tdengine for the Function Summary API, increasing test reliability. Overall impact: higher observability, throughput, and reliability in model monitoring; demonstrated API design, streaming data handling, time-series analytics, and CI-quality improvements.
