AWS re:Invent 2020: Data modeling with Amazon DynamoDB – Part 1

Amazon DynamoDB is popular due to its flexible billing model and ability to scale without performance degradation. It is a common choice in serverless and high-scale applications. But modeling your data with DynamoDB requires a different approach than modeling in traditional relational databases. Alex DeBrie is an AWS Data Hero, recognized for his work with DynamoDB, and author of The DynamoDB Book, a comprehensive guide to data modeling. In Part 1 of this two-part session, see how modeling with DynamoDB is different than a traditional relational database, and learn some foundational elements of data modeling with DynamoDB.

This is such a freaking wonderful presentation. So nice and clear with the examples. Excellent.

[JanekBogucki]

Very engaging presentation with useful techniques outlined clearly. It does pose the question of where the dividing line between a design pattern and a workaround for missing functionality lies.

[harjos]

Awesome presentation. worth every minute!

Maybe Mr Rick Houlihan continue helping our AWS Community. And I hope he takes a look how he introduces any topic or guest. Entonation and speed, a little better, less flat talking. Despite all, I really thank to all of you for every detail in this video. This is not a Daily News report but an updating event. Thanks.

DynamoDB has it's applications but I don't like the pitch as a general database.

It's basically: _yea but what if you want to scale your TODO application to the moon?? all it takes is just spewing inconsistent data everywhere and reinventing JOINs using string concatenation._

Interested to know how dynamo db can handle agile requirements. As schema and requirement changes...

I don't have a good understanding of joins in sql. At 10:55, which part of hashed partitions prevent nosql from having joins?

[amosfeldman]

Is there a playlist for the "Re:Invent" videos? I see one for the "Re:Inforce" ones?

How does AWS Amplify handle data access patterns since it doesn’t ask the user to define them when the user is defining relationships? I assume it just sets up a lot of global secondary indexes which will consume way more WCUs and make it way more expensive to add to your data than if you set everything up manually

Dynamodb to the rescue! Its hard but its hawd

7:35 that flat line violates the second law of thermodynamics to say the least. :/

I want to see how that actor/movie key works when you have something like Eddie Murphy and The Nutty Professor. Maybe that just wasn't a good example table, or I'm missing something? FYI, in that movie (like many other movies), the actor plays more than 1 role.

I love your work Alex. You just say “right” far too much.:)
