Amazon S3 Tables with Amazon Redshift gives you a powerful combination for analytical workloads on Apache Iceberg tables. But as query volumes grow, small inefficiencies compound. For example, repeated queries, such as dashboards refreshing hourly or analysts running the same joins throughout the day, scan data directly from Amazon Simple Storage Service (Amazon S3) every time. The fully qualified three-part table references (database@catalog.schema.table) add friction for business intelligence (BI) tools and end users who expect simpler SQL syntax. And without tuning the way S3 Tables organizes your data files, queries read more files than necessary. When you address these three areas, your S3 Tables queries in Amazon Redshift become faster, simpler, and more cost-efficient, whether you’re powering a recurring dashboard or supporting ad hoc analysis at scale.
This is the third post in our S3 Tables and Amazon Redshift series. The first post covered getting started…
