AWS Certified Data Analytics Specialty 2021 – Hands-On - Redshift Resizing (Elastic Versus Classic) and New Redshift Fea

The video tutorial explains how to resize Amazon Redshift clusters using Elastic and Classic Resize methods. Elastic Resize allows quick addition or removal of nodes with minimal downtime, while Classic Resize is used for changing node types, which can take longer. Snapshot Restore Resize is a strategy to minimize downtime during Classic Resize. New features like RA3 nodes and Data Lake Export are introduced, allowing independent scaling of compute and storage and exporting queries to S3 in Parquet format.

How do RA3 nodes differ from previous node types in terms of capacity scaling?

What advantages does the Parquet format offer when exporting Redshift queries to S3?
