With support for Apache Iceberg v3, Amazon Redshift users can now create and upgrade tables featuring default column values, row lineage metadata, and efficient deletion vectors. These additions facilitate schema evolution, incremental data processing, and high-frequency update workloads in data lakes.
Redshift’s implementation allows users to define default values simplifying table modifications, track row identities and update sequences for change data capture, and benefit from compressed bitmap deletion vectors that enhance read/write performance. Both provisioned and serverless Redshift clusters with Graviton processors support these capabilities.
