A Practical Guide to Using Sigma with Databricks
Blog post from Sigma
Architecting Databricks for use with analytics platforms such as Sigma involves crucial decisions regarding the choice of SQL warehouses, table types, and partitioning strategies. The article compares Classic and Serverless SQL warehouses, highlighting the differences in start-up times, cost implications, and suitability for different workloads, with Serverless offering more elasticity despite higher costs. It also emphasizes the Medallion Architecture for data design, which categorizes data into Bronze, Silver, and Gold levels to enhance data quality and processing efficiency using Delta Lake protocols. This architecture supports various data formats, with Delta tables providing significant advantages through ACID transactions and schema evolution. Proper partitioning strategies are vital for optimizing query performance, as inappropriate partitioning can slow down data retrieval significantly. Overall, the article underscores the benefits of using Serverless SQL warehouses and Delta tables within the Medallion Architecture to optimize performance and cost-effectiveness in Databricks integrations with Sigma.
