How does Databricks SQL compare to Snowflake for analytics workloads?

Databricks SQL (built on Delta Lake and Photon engine) delivers strong performance for mixed analytics/ML workloads and benefits from the unified Databricks Lakehouse platform. Snowflake provides a cleaner separation of roles (data engineers vs. analysts) and better native data sharing capabilities across organizations.

What are the key cost optimization strategies for cloud data warehouses?

Cost optimization includes clustering/partitioning tables to reduce data scanned, using materialized views for repeated queries, implementing workload management (WLM) to prevent runaway queries, auto-suspending idle compute clusters (Snowflake virtual warehouses), and using result caching to avoid recomputing identical queries.

How do cloud data warehouses handle real-time data ingestion?

Snowflake Snowpipe and Dynamic Tables enable near-real-time loading from Kafka and S3. BigQuery supports streaming inserts at up to 1 million rows/second. Redshift Streaming Ingestion connects directly to Amazon Kinesis. For sub-second latency, dedicated streaming engines (Apache Flink, ksqlDB) pre-aggregate before loading to the warehouse.
