Appendix

Managing column compression

Amazon Redshift's columnar architecture stores data columns upon columns on disk. Analytical queries select a subset of the columns and perform aggregation on millions to billions of records. The columnar architecture reduces the I/O by selecting a subset of the columns, thus improving query performance. When data is ingested into the Amazon Redshift table, it provides three to four times compression. This further reduces the storage footprint, which, in turn, reduces I/O and hence improves query performance. Reducing the storage footprint also saves you money. Amazon Redshift Advisor provides recommendations for compressing any uncompressed tables.

In this recipe, you will learn how Amazon Redshift automatically applies compression to new and existing tables. You will also learn how column-level compression can be modified for existing columns.

Serverless Architectures with AWS

Serverless Architectures with AWS

Serverless Architectures with AWS teaches you how to build serverless applications on AWS—applications that do not require the developer to provision, scale, or manage any servers. Using an event-driven approach and AWS Lambda as the primary service, the book explains the many benefits of serverless architectures. By the end of the book, you will be ready to create and run your first serverless application that takes advantage of the high availability, security, performance, and scalability of AWS. With this new architecture, you will be able to focus on your product instead of worrying about managing and operating servers to run it.
