Let’s walk through some of the recent key launches, including the new announcements at AWS re:Invent 2024.

Industry-leading price-performance

Amazon Redshift offers up to three times better price-performance than alternative cloud data warehouses. Amazon Redshift scales linearly with the number of users and volume of data, making it an ideal solution for both growing businesses and enterprises. For example, dashboarding applications are a very common use case in Redshift customer environments where there is high concurrency and queries require quick, low-latency responses. In these scenarios, Amazon Redshift offers up to seven times better throughput per dollar than alternative cloud data warehouses, demonstrating its exceptional value and predictable costs.

Performance improvements

Over the past few months, we have introduced a number of performance improvements to Redshift. First query response times for dashboard queries have significantly improved by optimizing code execution and reducing compilation overhead. We have enhanced data sharing performance with improved metadata handling, resulting in data sharing first query execution that is up to four times faster when the data sharing producer’s data is being updated. We have enhanced autonomics algorithms to generate and implement smarter and quicker optimal data layout recommendations for distribution and sort keys, further optimizing performance. We have launched new RA3.large instances, a new smaller size RA3 node type, to offer better flexibility in price-performance and provide a cost-effective migration option for customers using DC2.large instances. Additionally, we have rolled out AWS Graviton in Serverless, offering up to 30% better price-performance, and expanded concurrency scaling to support more types of write queries, enabling an even greater ability to maintain consistent performance at scale. These improvements collectively reinforce Amazon Redshift’s focus as a leading cloud data warehouse solution, offering unparalleled performance and value to customers.

General availability of multi-data warehouse writes

Amazon Redshift allows you to seamlessly scale with multi-cluster deployments. With the introduction of RA3 nodes with managed storage in 2019, customers obtained flexibility to scale and pay for compute and storage independently. Redshift data sharing, launched in 2020, enabled seamless cross-account and cross-Region data collaboration and live access without physically moving the data, while maintaining transactional consistency. This allowed customers to scale read analytics workloads and offered isolation to help maintain SLAs for business-critical applications. At re:Invent 2024, we announced the general availability of multi-data warehouse writes through data sharing for Amazon Redshift RA3 nodes and Serverless. You can now start writing to shared Redshift databases from multiple Redshift data warehouses in just a few clicks. The written data is available to all the data warehouses as soon as it’s committed. This allows your teams to flexibly scale write workloads such as extract, transform, and load (ETL) and data processing by adding compute resources of different types and sizes based on individual workloads’ price-performance requirements, as well as securely collaborate with other teams on live data for use cases such as customer 360.

General availability of AI-driven scaling and optimizations

The launch of Amazon Redshift Serverless in 2021 marked a significant shift, eliminating the need for cluster management while paying for what you use. Redshift Serverless and data sharing enabled customers to easily implement distributed multi-cluster architectures for scaling analytics workloads. In 2024, we launched Serverless in 10 more regions, improved functionality, and added support for a capacity configuration of 1024 RPUs, allowing you to bring larger workloads onto Redshift. Redshift Serverless is also now even more intelligent and dynamic with the new AI-driven scaling and optimization capabilities. As a customer, you choose whether you want to optimize your workloads for cost, performance, or keep it balanced, and that’s it. Redshift Serverless works behind the scenes to scale the compute up and down and deploys optimizations to meet and maintain the performance levels, even when workload demands change. In internal tests, AI-driven scaling and optimizations showcased up to 10 times price-performance improvements for variable workloads.

Seamless Lakehouse architectures

Lakehouse brings together flexibility and openness of data lakes with the performance and transactional capabilities of data warehouses. Lakehouse allows you to use preferred analytics engines and AI models of your choice with consistent governance across all your data. At re:Invent 2024, we unveiled the next generation of Amazon SageMaker, a unified platform for data, analytics, and AI. This launch brings together widely adopted AWS ML and analytics capabilities, providing an integrated experience for analytics and AI with a re-imagined lakehouse and built-in governance.

General availability of Amazon SageMaker Lakehouse

Amazon SageMaker Lakehouse unifies your data across Amazon S3 data lakes and Redshift data warehouses, enabling you to build powerful analytics and AI/ML applications on a single copy of data. SageMaker Lakehouse provides the flexibility to access and query your data using Apache Iceberg open standards so that you can use your preferred AWS, open source, or third-party Iceberg-compatible engines and tools.

Amazon Redshift SQL analytics on Amazon S3 Tables

At re:Invent 2024, Amazon S3 introduced Amazon S3 Tables, a new bucket type that is purpose-built to store tabular data at scale with built-in Iceberg support. With table buckets, you can quickly create tables and set up table-level permissions to manage access to your data lake. Amazon Redshift introduced support for querying Iceberg data in data lakes last year, and now this capability is extended to seamlessly querying S3 Tables. S3 Tables customers create are also available as part of the Lakehouse for consumption by other AWS and third-party engines.

Data lake query performance

Amazon Redshift offers high-performance SQL capabilities on SageMaker Lakehouse, whether the data is in other Redshift warehouses or in open formats. We enhanced support for querying Apache Iceberg data and improved the performance of querying Iceberg up to threefold year-over-year. A number of optimizations contribute to these speed-ups in performance, including integration with AWS Glue Data Catalog statistics, improved data and metadata filtering, dynamic partition elimination, faster/parallel processing of Iceberg manifest files, and scanner improvements. In addition, Amazon Redshift now supports incremental refresh support for materialized views on data lake tables to eliminate the need for recomputing the materialized view when new data arrives, simplifying how you build interactive applications on S3 data lakes.

Simplified ingestion and near real-time analytics

In this section, we share the improvements regarding simplified ingestion and near real-time analytics that enable you to get faster insights over fresher data.

Zero-ETL integration with AWS databases and third-party enterprise applications

Amazon Redshift first launched zero-ETL integration between Amazon Aurora MySQL-Compatible Edition, enabling near real-time analytics on petabytes of transactional data from Aurora. This capability has since expanded to support Amazon Aurora PostgreSQL-Compatible Edition, Amazon Relational Database Service (Amazon RDS) for MySQL, and Amazon DynamoDB, and includes additional features such as data filtering to selectively extract tables and schemas using regular expressions, support for incremental and auto-refresh materialized views on replicated data, and configurable change data capture (CDC) refresh rates.

Building on this innovation, at re:Invent 2024, we launched support for zero-ETL integration with eight enterprise applications, specifically Salesforce, Zendesk, ServiceNow, SAP, Facebook Ads, Instagram Ads, Pardot, and Zoho CRM. With this new capability, you can efficiently extract and load valuable data from your customer support, relationship management, and Enterprise Resource Planning (ERP) applications directly into your Redshift data warehouse for analysis. This seamless integration eliminates the need for complex, custom ingestion pipelines for ingesting the data, accelerating time to insights.
