Over the last year, Amazon Redshift added several performance optimizations for data lake queries across multiple areas of query engine such as rewrite, planning, scan execution and consuming AWS Glue Data Catalog column statistics. In this post, we highlight the performance improvements we observed using industry standard TPC-DS benchmarks. Overall execution time of TPC-DS 3 TB benchmark improved by 3x. Some of the queries in our benchmark experienced up to 12x speed up.

Unlocking the true value of data often gets impeded by siloed information. Traditional data management—wherein each business unit ingests raw data in separate data lakes or warehouses—hinders visibility and cross-functional analysis. A data mesh framework empowers business units with data ownership and facilitates seamless sharing. However, integrating datasets from different business units can present several […]

This post shares the simple steps you can take to use the new Amazon Redshift usage controls feature to monitor and control your usage and associated cost for Amazon Redshift Spectrum and Concurrency Scaling features. Redshift Spectrum enables you to power a lake house architecture to directly query and join data across your data warehouse and data lake, and Concurrency Scaling enables you to support thousands of concurrent users and queries with consistently fast query performance.

This post demonstrates how to develop a comprehensive, wave-based application migration methodology for a complex project to modernize a traditional MPP data warehouse with Amazon Redshift. It provides best practices and lessons learned by considering business priority, data dependency, workload profiles and existing service level agreements (SLAs).

With Amazon Redshift Spectrum, you can query the data in your Amazon Simple Storage Service (Amazon S3) data lake using a central AWS Glue metastore from your Amazon Redshift cluster. This capability extends your petabyte-scale Amazon Redshift data warehouse to unbounded data storage limits, which allows you to scale to exabytes of data cost-effectively. Like Amazon EMR, you get the benefits of open data formats and inexpensive storage, and you can scale out to thousands of Redshift Spectrum nodes to pull data, filter, project, aggregate, group, and sort. Like Amazon Athena, Redshift Spectrum is serverless and there’s nothing to provision or manage. You only pay $5 for every 1 TB of data scanned. This post discusses how to configure Amazon Redshift security to enable fine grained access control using role chaining to achieve high-fidelity user-based permission management.

Redshift Spectrum is a feature of Amazon Redshift that allows you to query data stored on Amazon S3 directly and supports nested data types. This post discusses which use cases can benefit from nested data types, how to use Amazon Redshift Spectrum with nested data types to achieve excellent performance and storage efficiency, and some […]
