## AI overview

The article describes how Localytics used DynamoDB to deduplicate billions of daily datapoints and examined schema changes to reduce storage costs. It discusses duplicate UUIDs, a 30-day deduplication history, and the limitations of a naive schema.

## Source excerpt

Amazon's DynamoDB is a great technology: it's easy to set up and provides all the benefits of an infinitely scalable distributed database without the operational overhead. Unfortunately, DynamoDB can also be very expensive for high volume, high throughput storage. This post will show how we were
