Redshift Optimization by AWS

Working with the experts at AWS, we augmented our existing Redshift Administration Block to include performance optimization views, explores and dashboards. We’ve also included a guide to help users identify and diagnose performance issues, as well as suggested actions to take based on those issues. We include several pieces of analysis:

• Performance Overview Dashboard - offers users an aggregate view of performance across all clusters, tasks, and users
• Query Inspector Dashboard - provides comprehensive information about a specific query, enabling users to understand the factors contributing to performance (e.g. bytes scanned, seconds to run, distribution, bytes broadcasted, etc.)

Based on the information provided by the query inspector, users should take corrective action to improve query performance. In this Block, we have a matrixed guide offering remedial actions for poorly performing queries.
