Amazon Announces Redshift, a Petabyte-scale Data Warehouse Service

Werner Vogels, CTO of Amazon, recently reported, “We are excited to announce the limited preview of Amazon Redshift, a fast and powerful, fully managed, petabyte-scale data warehouse service in the cloud. Amazon Redshift enables customers to obtain dramatically increased query performance when analyzing datasets ranging in size from hundreds of gigabytes to a petabyte or more, using the same SQL-based business intelligence tools they use today. Customers have been asking us for a data warehouse service for some time now and we’re excited to be able to deliver this to them.”

Vogels goes on, “Amazon Redshift uses a variety of innovations to enable customers to rapidly analyze datasets ranging in size from several hundred gigabytes to a petabyte and more. Unlike traditional row-based relational databases, which store data for each row sequentially on disk, Amazon Redshift stores each column sequentially. This means that Redshift performs much less wasted IO than a row-based database because it doesn’t read data from columns it doesn’t need when executing a given query. Also, because similar data are stored sequentially, Amazon Redshift can compress data efficiently, which further reduces the amount of IO it needs to perform to return results.”
