Optimize Amazon S3 Tables queries with Amazon Redshift
Big Data Blog
This article explains how to optimize Amazon S3 Tables queries using Amazon Redshift through three key optimization techniques.
- Create external schemas to simplify query syntax from three-part to two-part notation
- Build materialized views to store pre-computed results locally in Redshift
- Configure S3 Tables compaction strategies (sort, z-order, binpack) matching query patterns
- Use IAM federation with SESSION credentials for new applications and interactive users
- Materialized views support incremental refresh for INSERT, DELETE, UPDATE operations
- Sort compaction optimizes single-column filters; z-order handles multi-column filters
- Coordinate snapshot retention with materialized view refresh intervals to avoid full recomputes
- Monitor compaction operations via AWS CloudTrail management events
These three approaches work together to make S3 Tables queries faster, simpler, and more cost-efficient for both recurring dashboards and ad hoc analysis at scale.
