Fair enough! IMO, it's worth it :). You could spend a bunch of time cobbling together free resources, and you'd still only get about 30% of what's in the book. How much is your time worth as a software engineer? That said, a

Waves Author here. Happy to answer any questions folks have about the book, about DynamoDB, or about self-publishing. NoSQL modeling is waaay different than relational modeling. I think a lot of NoSQL advice out there is pretty bad, which

One note on this -- if you have an LSI, you can't have an item collection larger than 10GB, where an item collection refers to all the items with the same partition key in your main table and your LSI. A DynamoDB table with an LSI ca

I just answered this on Twitter, but I think there are two instances where it's a no-brainer to use DynamoDB: - High-scale situations where you're worried about performance of a relational database, particularly joins, as it scale

It's different than a relational database in that you need to model your data to your patterns, rather than model your data and then handle your patterns. Once you learn the principles, it really is like clockwork. It changes your proc

Thank you! Glad you found DynamoDBGuide.com helpful :) Yep, I do talk about aggregations in the book. One strategy that I've discussed is available in a blog post here[0] and involves using DynamoDB Transactions to handle aggregates. I

Great point! It was originally about both of these things, but the storage aspect isn't discussed much anymore because it's really not a concern. The data integrity issue is still a concern, and I talk about that in the book. You

I think there are some features of DynamoDB that are miles ahead of other databases: - Billing model. Pay for reads and writes directly rather than trying to guess how your queries turn into CPU & RAM. Also able to scale reads and write

Thanks! Honestly, I'm right with you. I would love a physical copy. I did a bit of research and didn't find any great options for making a physical copy of a self-published book for the number of copies I'm expecting to sell

The concepts are definitely applicable. You'll need to do some small work to translate vocabulary and work around a slightly different feature set, but most of it should work for you. And yep, Cassandra is pretty similar to DynamoDB. B
