An S3 data lake has the potential to store exabytes of data, and with Spectrum, Amazon Redshift can query it all. Redshift Spectrum is a powerful feature of Amazon Redshift that allows users to query data on S3 data lake, as if they were any other tables locally stored in your data warehouse cloud cluster. This gives you the flexibility to store highly structured, frequently accessed data in Redshift, keep exabytes of structured and unstructured data in S3, and query seamlessly across both to provide unique insights that you would not be able to obtain by querying independent datasets. With Redshift Spectrum, you can query open file formats you already use, such as Avro, CSV, Grok, JSON, ORC, Parquet, and more, directly in S3. Redshift allows you to extend your queries to your Amazon S3 data lake without moving or transforming data. As a matter of fact, AWS calls it a Data Lake House. Redshift is unique because it's the only solution that is both a data warehouse and a data lake. Redshift is fully integrated with other AWS services in the AWS ecosystem such as VPC’s, KMS and IAM for security, S3 for data lake integration and backups, EC2s for its cluster implementation, and CloudWatch for monitoring. Redshift started out as a PostgreSQL fork, but completely rewrote the storage engine to be columnar, made it an OLAP relational data store by adding analytics functions such as window operations, and added parallel processing (MPP) for endless scaling. What is Amazon Redshift?Īmazon Redshift is a fully managed, petabyte-scale cloud data warehouse service within the AWS platform ecosystem that allows you to centralize all of your insightful data into a single data repository on the cloud. In this article, intended for a technical audience, we’ll share a detailed discussion of each of those benefits on Amazon Redshift, highlighting some of its best features and how you would benefit from including it as part of your organization’s data platform. They also allow for resource auto-scaling in seconds, cloning, replications, in-house auto-ingestion, and more. Cloud data warehouses bring enhanced performance for queries and data storage and enable easy data sharing across departments, regions, clients, or even the public. While increased scalability and lower maintenance costs drove the initial push to cloud data warehousing, the pace of migration is accelerating now due to the dramatic expansion upon the core functionalities of a traditional data warehouse. IT organizations know this and have begun prioritizing database cloud migration projects over the last few years. Using the power of the modern public cloud, it is increasingly realistic. This is the story of almost every data warehouse project. “We want to centralize data across our organization using a scalable solution with low maintenance requirements.”
