Endigest AI Core Summary
This post covers Databricks' Predictive Optimization (PO) in Unity Catalog, which became the default platform behavior in 2025 for autonomous lakehouse table maintenance.
•PO automatically runs OPTIMIZE, VACUUM, CLUSTER BY, and ANALYZE based on observed query and write patterns, eliminating manual table tuning
•Automatic Statistics (GA) delivered up to 22% faster queries using stats-on-write (7-10x more performant than ANALYZE TABLE) and background refresh
•Optimized VACUUM using the Delta transaction log achieved up to 6x faster execution and 4x lower compute cost compared to standard directory listing approaches
•Automatic Liquid Clustering (GA) analyzes query telemetry to auto-select optimal clustering keys, reducing data scanned with zero manual configuration
•
Upcoming 2026 features include Auto-TTL for automated time-to-live row deletion and a Data Governance Hub dashboard for PO observability and ROI tracking
