AWS Certified Data Analytics Specialty 2021 - Hands-On! - Amazon DynamoDB Provisioned Throughput

The video tutorial explains how to compute provisioned throughput in DynamoDB, focusing on read and write capacity units (RCU and WCU). It covers the differences between strongly consistent and eventually consistent reads, and provides examples of calculating RCU and WCU. The tutorial also addresses throttling issues, such as hot keys, and suggests solutions like exponential backoff and using DynamoDB Accelerator (DAX). Finally, it demonstrates how to configure DynamoDB tables, including using the capacity calculator and setting up autoscaling.
