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

The video tutorial explains the internal workings of DynamoDB, focusing on partitions. It covers the limits of partitions in terms of RCU, WCU, and data size. The tutorial describes how data is distributed using a hashing algorithm and how to calculate the number of partitions needed based on capacity and size. It also discusses the even distribution of RCU and WCU across partitions and the concept of hot partitions, which can lead to throttling. Understanding these concepts is crucial for managing DynamoDB tables effectively.

What is the maximum number of Read Capacity Units (RCU) and Write Capacity Units (WCU) that a single partition can handle in DynamoDB?

Explain how the hashing algorithm works in determining which partition a user ID will go to in DynamoDB.

How can you calculate the total number of partitions needed for a DynamoDB table based on its size and capacity?

Describe the distribution of RCU and WCU across partitions in a DynamoDB table.

What happens when a user ID is frequently accessed in a partition, and how does it affect the partition's performance?
