MLflow trace storage in Unity Catalog

Stores MLflow traces in OpenTelemetry-format Delta tables in Unity Catalog, linked to an MLflow experiment, with no per-experiment trace limit, access governed by Unity Catalog table permissions, and traces open to SQL, Genie Code, AI/BI dashboards and any Spark-based tool. OpenTelemetry clients can send spans to a Databricks-hosted OTLP endpoint; since November 2026 Anthropic's Claude Platform can export its traces to Databricks MLflow this way, an Anthropic feature in beta. Since November 2, 2026, a managed warehouse for MLflow (Beta) lets users view traces stored in Unity Catalog in the MLflow UI without choosing a SQL warehouse: MLflow runs the trace queries on a SQL warehouse it creates in the workspace when the workspace supports it, and on serverless compute otherwise; workspace admins turn it on from the Previews page.
