The architecture uses Lakeflow Auto Loader for NDJSON ingestion, Spark Declarative Pipelines with 46 data quality expectations across bronze/silver/gold tiers, and liquid clustering for 1-3 second query response times. Two serving paths are deliberately separated: Lakebase (Postgres-backed) handles millisecond-latency replay reads, while DBSQL handles bursty analytical queries. AI features include a Genie natural-language-to-SQL scout interface, Vector Search for similar player lookups, and an Agent Bricks supervisor that orchestrates Genie, Vector Search, a Unity Catalog xG model, and Claude via the Unity AI Gateway to generate opponent dossiers. All model calls are traced in MLflow with deterministic fallbacks. The post frames this as a blueprint for closing the 'usability gap' in high-frequency operational data across any industry. ## Full article daily.dev links to this article rather than hosting it.
