Chapter 10. Programming for the NoSQL database service: DynamoDB

This chapter covers

The DynamoDB NoSQL database service
Creating tables and secondary indexes
Integrating DynamoDB into your service stack
Designing a key-value optimized data model
Tuning performance

Scaling a traditional, relational database is difficult because transactional guarantees (atomicity, consistency, isolation, and durability, also known as ACID) require communication among all nodes of the database. The more nodes you add, the slower your database becomes, because more nodes must coordinate transactions between each other. The way to tackle this has been to use databases that don’t adhere to these guarantees. They’re called NoSQL databases.
