Distribution Styles and Sort Keys

 Distribution Styles: Redshift allows you to choose between distribution styles—EVEN, KEY, or ALL—when designing your tables. The distribution style affects how data is distributed across compute nodes. Choosing the right distribution style based on your workload patterns can have a significant impact on query performance. Analyze your query patterns and data access patterns to determine the most appropriate distribution style for your tables.

 Sort Keys: Defining sort keys on your tables helps improve query performance by storing data in sorted order. Redshift leverages zone maps and predicate pushdown optimization to skip irrelevant data blocks during query execution, resulting in faster query performance. Identify columns frequently used in WHERE clauses and JOIN conditions, and consider using them as sort keys to maximizing performance.
