Build with DynamoDB | S1 E5 – A Data Modeling Use Case Deep Dive

Join Amazon DynamoDB experts as they take a relational data model from a real-world use case and demonstrate how to implement it step by step in DynamoDB. Come with questions!

I watch everything with Rick Houlihan in it. It really helps me finally understand so much stuff. If it's to much information for you all at once then watch it over and over. I did. Every time I get more valuable information. I highly recommend his reinvent stuff. It's the only relevant reinvent video to watch.

I'm gonna have to watch this a few more times to "get it" -- so much overloading, and more GSIs than you usually show. Like others have said, it would be really helpful to link these talks to sample code and data we can play with and understand.

In the future - please put links from the video to the description, for example from 38:19

great series. It went from too slow to rocket speed though. For me, episode 4 was a good pace so i could ingest everything and felt my time was most utilized. It would be great if you could make one more installment and just go through the code to create the tables and a few queries for your more complex example. (movie example would be great). I never find AWS code samples that represented more complex scenarios. Would be better if there was a github repo. Thanks!

I'm late to the party, but wouldn't Collections and Items be a many to many relationship? A collection can be associated to multiple items, but an item could also be associated to multiple collections. I could have a collection containing Lord of the Rings, and someone else can have their collection with Lord of the Rings as well. Am I missing something?

After watching 5 Mins of this episode, I had the feeling that I was about to understand very little -.-

finally had that AHA! researching and reading all things dynamodb and made a million crappy tables in the NoSQL Workbench and single table design has finally clicked for all but one thing that continues to elude me and i really hope someone can shed some light on it. So Lets say i am an online travel site. On my home page (as most travel sites do), there will be perhaps a carousel or list showing some featured tours, perhaps a similar list of tours that are nearly fully booked or perhaps a list of tours that are currently part of a promotional could such use cases work with dynamo? My concern is that if i set a GSI of "status" on a tour/holiday package, it will ALWAYS be read based on the number of people viewing the site. Wouldn't this risk the GSI becoming a hot partition??

38:06 did someone noticed how he just freestyle like Em?

I don't really understand if we create these collections or if it's automatic, but where we define the prefixo "XXX" to collections?

[sardesaisantosh]

I think if you plot clearly GSI like base table and define the query (access patterns) that particular GSI will support with some data populated, it will help to understand, Rick is like he is riding on a rocket. super fast - why so? don't know. hardly someone may follow.

Oh yeah they call him the streak, fastest thing on 2 feet.

Too fast speaking. Humans don’t learn like robots lol
