• Clusters and Nodes in Amazon Redshift https://docs.aws.amazon.com/redshift/latest/mgmt/working-with-clusters.html#rs-about-clusters-and-nodes

RedShift Schema and Table Design

• Choosing Sort Keys https://docs.aws.amazon.com/redshift/latest/dg/t_Sorting_data.html Sorting enables efficient handling of range-restricted predicates.
• Distribution Styles https://docs.aws.amazon.com/redshift/latest/dg/c_choosing_dist_sort.html
• Tutorial: Tuning Table Design https://docs.aws.amazon.com/redshift/latest/dg/tutorial-tuning-tables.html in this tutorial, you will learn how to optimize the design of your tables. You will start by creating tables based on the Star Schema Benchmark (SSB) schema without sort keys, distribution styles, and compression encodings.
