Azure SQL DataWarehouse Reflections (Cloud Services)
Azure SQL DataWarehouse is here and being pushed as the answer to huge structured data stores in the cloud, but what does that mean to you? Reflecting on a large-scale Azure SQLDW project, this session gathers together learnings, successes, failures and general opinions into a crash course in using Azure SQL DataWarehouse “properly”.
We'll start by quickly putting the technology in context, so you know WHEN to use it, WHERE its appropriate and WHY it works the way it does.
• Introducing the SQLDW technology
• Explaining distributions & performance
• Explaining polybase
We will then dive into HOW to use it, looking at some real-life design patterns, best practice and some “tales from the trenches” from a recent large Azure SQLDW project.
• Performance tips & tricks (designing for minimal data movement, managing distribution skew, CTAS, Resource classes and more)
• ETL Patterns (Surrogate keys & Orchestration)
• Common Mistakes & Pitfalls
• Conclusions & Recommendations
