CoreAmazon Redshift
Managed columnar data warehouse for large-scale analytical queries and aggregations.
Key points
- Redshift is optimized for OLAP rather than high-volume row-oriented transactions.
- Data layout, compression, concurrency, workload management, and source ingestion affect performance and cost.
- Use S3 as a complementary lake and choose serverless or provisioned warehouse capacity from workload behavior where supported.
Best-known use cases
- Run BI queries over large curated analytical datasets.
- Consolidate data for repeatable warehouse reporting.
What candidates often confuse it with
- Redshift is a warehouse; RDS/Aurora is an OLTP relational database.
- Redshift stores warehouse data; Athena queries S3 directly without a warehouse.
Key takeaway
Choose Redshift for sustained analytical warehouse workloads, not transactional application storage.
