7 Common DynamoDB Patterns for Modeling and Building an App with Alex De Brie

DynamoDB is one of the most common databases for building serverless applications. But we don't know how to model our data for fitting in a DynamoDB table. One of the best practices for modeling data is the single table design that is a new concept that we need to learn.

In this video Alex De Brie - AWS Data Hero, will show us 7 patterns and good practices that will help us with the modeling and building an application in real life.

00:00 - Introduction
04:09 - Why DynamoDB?
07:37 - Some foundational concepts for getting started
15:16 - Starting with the demo
19:05 - How to model your data?
26:11 - How to keep up with data changing in the single table design?
30:48 - Walking through the code
37:42 - Abstract class for base entities
46:02 - getClient function to improve the performance
