Unlock cost savings with incremental snapshot billing for Amazon Redshift Serverless and Amazon Redshift RG

Starting June 8, 2026, Amazon Redshift is introducing an incremental snapshot billing model for Amazon Redshift Serverless and Amazon Redshift RG (provisioned instances powered by AWS Graviton). With this enhancement, you pay only for the unique data blocks across your active manual snapshots within your account. This delivers significant cost savings for customers who have multiple snapshots that contain largely identical data blocks. In this post, you will learn how the new incremental snapshot billing model works, the customer use cases it addresses, and how it helps you optimize costs while improving your Recovery Point Objective (RPO).

How Zynga scaled multi-warehouse data governance with Amazon Redshift federated permissions

In this post, we walk through how Zynga adopted Amazon Redshift federated permissions and AWS IAM Identity Center to enforce consistent, tiered data access across provisioned and serverless Amazon Redshift environments without building custom synchronization pipelines.

A systematic approach to benchmarking SQL processing engines on AWS

Selecting the right SQL processing solution for large-scale data analytics is a critical decision for organizations. As data volumes grow exponentially, the technology landscape has evolved to offer diverse options for processing and analyzing this information efficiently. This post presents a systematic framework for evaluating and benchmarking SQL processing engines on AWS, using Apache JMeter to conduct practical performance testing at scale.

Meet Amazon Redshift RG – AWS Graviton-based instances with an integrated data lake query engine delivering up to 2.4x better performance at 30% lower price than RA3

On May 12, 2026, we announced the general availability of Amazon Redshift RG instances, powered by AWS Graviton processors. RG instances are up to 2.2x as fast for data warehouse workloads and up to 2.4x as fast for data lake workloads, all at 30% lower price per vCPU compared to RA3 instances. RG instances support all data lake formats supported by RA3 and eliminate Amazon Redshift Spectrum’s per-TB scanning charges. RG instances feature a custom-built integrated vectorized query engine, making them a more performant and cost-effective foundation for unified analytics. We are launching with two instance sizes: rg.xlarge and rg.4xlarge, with additional sizes coming later this year.

How to use streamlined permissions for Amazon S3 Tables and Iceberg materialized views

In this post, we walk through how to set up and manage S3 Tables in the AWS Glue Data Catalog, create and query Iceberg materialized views, and configure access controls that work across your analytics stack with IAM-based authorization.

Getting started with Apache Iceberg write support in Amazon Redshift – Part 2

Amazon Redshift now supports DELETE, UPDATE, and MERGE operations for Apache Iceberg tables stored in Amazon S3 and Amazon S3 table buckets. With these operations, you can modify data at the row level, implement upsert patterns, and manage the data lifecycle while maintaining transactional consistency using familiar SQL syntax. You can run complex transformations in Amazon Redshift and write results to Apache Iceberg tables that other analytics engines like Amazon EMR or Amazon Athena can immediately query. In this post, you work with datasets to demonstrate these capabilities in a data synchronization scenario.

Proactive monitoring for Amazon Redshift Serverless using AWS Lambda and Slack alerts

In this post, we show you how to build a serverless, low-cost monitoring solution for Amazon Redshift Serverless that proactively detects performance anomalies and sends actionable alerts directly to your selected Slack channels.
