This course covers the Architecture of Redshift, Columnar vs Row oriented databases, Introduce you to the AWS VPC, IAM role, and S3 bucket creation. You can master the SQL with best practices and learn a few admin activities which help to build an effective data warehouse. This course introduces compression/encoding techniques. You can learn to implement Workload management and monitor and tune long-running queries. I always noticed most of the data engineers are clueless about how data is retrieved from the database. Writing an optimized query is a must when dealing with big data, understanding the architecture and the movement of the data is very important to write the best query. Without prior knowledge on SQL, you can master the SQL and become a pro with this short 2 Hour tutorial.
