When we talk with customers, we hear that they want to be able to harness insights from data in order to make timely, impactful, and actionable business decisions. A common pattern with data-driven organizations is that they have many diﬀerent data sources they need to ingest into their analytics systems. This requires them to build manual data pipelines spanning across their operational databases, data lakes, streaming data, and data within their warehouse. As a consequence of this complex setup, it can take data engineers weeks or even months to build data ingestion pipelines. These data pipelines are costly, and the delays can lead to missed business opportunities. Additionally, data warehouses are increasingly becoming mission critical systems that require high availability, reliability, and security.
Amazon Redshift is a fully managed petabyte-scale data warehouse used by tens of thousands of customers to easily, quickly, securely, and cost-effectively analyze all their data at any scale. This year at re:Invent, Amazon Redshift has announced a number of features to help you simplify data ingestion and get to insights easily and quickly, within a secure, reliable environment.
In this blog, I introduce some of these new features that ﬁt into two main categories:
- Simplify data ingestion
- Amazon Redshift now supports auto-copy from Amazon S3 (available in preview). With this new capability, Amazon Redshift automatically loads the files that arrive in an Amazon Simple Storage Service (Amazon S3) location that you specify into your data warehouse. The files can use any of the formats supported by the Amazon Redshift copy command, such as CSV, JSON, Parquet, and Avro. In this way, you don’t need to manually or repeatedly run copy procedures. Amazon Redshift automates file ingestion and takes care of data-loading steps under the hood.
- With Amazon Aurora zero-ETL integration with Amazon Redshift, you can use Amazon Redshift for near real-time analytics and machine learning on petabytes of transactional data stored on Amazon Aurora MySQL databases (available in limited preview). With this capability, you can choose the Amazon Aurora databases containing the data you want to analyze with Amazon Redshift. Data is then replicated into your data warehouse within seconds after transactional data is written into Amazon Aurora, eliminating the need to build and maintain complex data pipelines. You can replicate data from multiple Amazon Aurora databases into the same Amazon Redshift instance to run analytics across multiple applications. With near real-time access to transactional data, you can leverage Amazon Redshift’s analytics and capabilities, such as built-in machine learning (ML), materialized views, data sharing, and federated access to multiple data stores and data lakes, to derive insights from transactional and other data.
- With the general availability of Amazon Redshift Streaming Ingestion, you can now natively ingest hundreds of megabytes of data per second from Amazon Kinesis Data Streams and Amazon MSK into an Amazon Redshift materialized view and query it in seconds. Learn more in this post.
- Make your data warehouse more secure and reliable
- You can now improve the availability of your data warehouse by choosing multiple Availability Zone (AZ) deployments. Multi-AZ deployments for your Amazon Redshift clusters are available in preview and reduce recovery times to seconds through automatic recovery. In this way, you can build solutions that are more compliant with the recommendations of the Reliability Pillar of the AWS Well-Architected Framework.
- With dynamic data masking (available in preview), you can protect sensitive information stored in your data warehouse and ensure that only the relevant data is accessible by users based on their roles. You can limit how much identifiable data is visible to users using multiple levels of policies so different users and groups can have different levels of data access without having to create multiple copies of data. Dynamic data masking complements other granular access control capabilities in Amazon Redshift including row-level and column-level security and role-based access controls. In this way, Dynamic Data Masking helps you meet requirements for GDPR, CCPA, and other privacy regulations.
- Amazon Redshift now supports central access controls for data sharing with AWS Lake Formation (available in public preview). You can now use Lake Formation to simplify governance of data shared from Amazon Redshift and centrally manage granular access across all data-sharing consumers.
There have been other interesting news for Amazon Redshift at re:Invent you might have already heard about:
- The general availability of Amazon Redshift integration for Apache Spark makes it easy to build and run Spark applications on Amazon Redshift and Redshift Serverless, opening up the data warehouse for a broader set of AWS analytics and machine learning solutions.
- AWS Backup now supports Amazon Redshift. AWS Backup allows you to define a central backup policy to manage data protection of your applications and can also protect your Amazon Redshift clusters. In this way, you have a consistent experience when managing data protection across all supported services.
Availability and Pricing
Multi-AZ deployments, central access control for data sharing with AWS Lake Formation, auto-copy from Amazon S3, and dynamic data masking are available in preview in US East (Ohio), US East (N. Virginia), US West (Oregon), Asia Pacific (Tokyo), Europe (Ireland), and Europe (Stockholm).
There is no additional cost for using auto-copy from Amazon S3 and near real-time analytics on transactional data. There is no extra charge for dynamic data masking and central access control for data sharing. For more information, see Amazon Redshift pricing.
These new capabilities take you one step further in analyzing all your data across data sources with simple data ingestion capabilities, while improving the security and reliability of your data warehouse.
