- 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.
