Materialized views in Databricks SQL enable low-latency analytics by pre-computing and incrementally refreshing query results. You can build them using pipe syntax to optimize complex aggregations and speed up dashboard performance on Lakehouse workloads.

Procedural SQL and stored procedures in DBSQL are used for ETL automation and governance. Recommended practices include encapsulating transformation logic within stored procedures to maintain data quality and orchestrate robust analytics pipelines on serverless warehouses.

Yes, Databricks SQL supports geospatial analytics using H3 indexing and ST_ functions. These capabilities allow you to perform location-aware analysis, such as spatial joins and polygon point containment checks, directly within your SQL queries.

Yes, DBSQL provides AI function integration through ai_query, ai_classify, and http_request. These functions enable data enrichment and Lakehouse federation by allowing you to query remote models and external data sources directly from SQL.

Serverless SQL warehouses provide faster start times and automatic scaling for variable analytics workloads, while classic warehouses offer more predictable performance for sustained heavy ETL. Choose serverless for low-latency analytics and classic for consistent procedural scripting.

Recursive CTEs in Databricks SQL allow you to query hierarchical or graph-structured data by repeatedly executing a query that references itself. They are essential for building advanced analytics pipelines that traverse organizational structures or dependency graphs.
