Summary

In this chapter, we leaned into the concept of item collections within DynamoDB, understanding when and how to use them, along with their advantages and key considerations, illustrated through practical examples.

The focus then shifted to breaking down data for vertical partitioning, exploring the pros and essential considerations associated with this approach. The discussion highlighted how vertical partitioning not only optimizes performance but also addresses challenges in evolving and extending the data model.

We explored the practical implications of vertical partitioning, showcasing its role in future-proofing the data model and enhancing extensibility, aspects crucial for maintaining flexibility and scalability in DynamoDB, especially in comparison to traditional NoSQL systems.

I recommend checking out the AWS official blog article on vertical partitioning authored by Mike and our colleague (3). It’s a valuable resource that complements the learnings...
