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.

If you're looking for large-scale aggregates for analytics (e.g. "What are my top-selling items last month?"), I have an Analytics supplement in the Plus package that includes notes on different patterns for analytics w/ DynamoDB.

Let me know if that helps!
