help Redshift (AWS) FAQ

What is Amazon Redshift used for?

Amazon Redshift is AWS's managed data warehouse for analytics and business intelligence workloads. Companies use it to run SQL queries over large structured datasets rather than serving live application transactions.

How is Redshift different from Amazon RDS?

Amazon RDS is usually used for transactional databases like PostgreSQL or MySQL, while Redshift is optimized for columnar analytics. Redshift is better suited to aggregations, reporting, and large scans across historical data.

What is Redshift Spectrum?

Redshift Spectrum lets Redshift query data stored in Amazon S3 without loading all of it into Redshift tables first. It is often used with data lake formats and AWS Glue Data Catalog metadata.

Does Redshift require managing servers?

Redshift has provisioned clusters and Redshift Serverless, so teams can choose how much infrastructure they want to manage. Redshift Serverless became generally available in 2022 and is aimed at reducing cluster administration.
