Auto-copy automatically ingests new data files from Amazon S3 into Redshift tables, simplifying data load management. With concurrency scaling enabled, Redshift dynamically adds cluster capacity to handle increased read and write workloads without performance degradation.

This feature is generally available for Redshift Serverless and RA3 Provisioned warehouses across all AWS regions supporting auto-copy, targeting customers with high-volume, time-sensitive ingestion needs. Documentation states performance benefits, but independent performance metrics are not reported.
