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 52:32 - Using ULIDs as unique, sortable identifiers 57:00 - Tracking reference counts with transactions 01:01:05 - Query operations in DynamoDB 01:04:00 - Many to many relationships Get the code: https://github.com/alexdebrie/dynamodb-instagram Find Alex in the internet - Twitter: https://twitter.com/alexbdebrie - The DynamoDB book: https://www.dynamodbbook.com/ 📼 Related videos ▪️ Interview with Rick Houlihan about DynamoDB and single table design: https://youtu.be/ZDIh1L5y2Q4 (part 1) and https://youtu.be/Hb3bqOQup10 (part 2) ▪️ Playlist on basic data modeling for DynamoDB step by step: https://www.youtube.com/playlist?list=PLGyRwGktEFqefq_8Kt-k-hGjN9LzBpCyp #foobar #serverless ☁️ Topics covered include: - DynamoDB -nosql databases - data modeling - best practices for database design - global index - partition key and sort key ⭐ SUBSCRIBE TO THIS CHANNEL: http://bit.ly/foobar-youtube ⭐SHARE THIS VIDEO: https://youtu.be/Q6-qWdsa8a4 ☆☆ FOLLOW ME ONLINE ☆☆ 🐦 Twitter: https://twitter.com/mavi888uy 📺 AWS Spanish Youtube Channel: https://bit.ly/aws-esp-yt 📷 Instagram: foobar_codes 📚 All my Serverless Courses: https://marcia.dev/courses/ ✍️ My blog - https://blog.marcia.dev ☆☆ ABOUT FOOBAR ☆☆ In this channel, you can find mostly coding tutorials related to cloud and serverless.
