Many production data bugs originate not from missing transactions, but from misunderstanding what transactions actually guarantee. Systems often wrap logic inBEGINandCOMMITand assume correctness follows automatically. Under concurrent load, these systems still oversell inventory, double-charge users

The system serves typical blog workloads such as “latest posts”, “most popular posts”, “posts by author”, and “posts by tag”, while also supporting administrative queries like user moderation and contact messages

It is designed to deliver single-digit millisecond performance at virtually any scale, without requiring developers to manage servers, storage, or replication. This article covers what DynamoDB is, how

After implementing horizontal scaling on servers and handling thousands of concurrent requests inScalability for Dummies — Part 1: Clones, performance may still degrade over time. Applications often slow down and eventually fail due to database limitations. Even with a perfectly scaled front end, th
