In this episode you will learn:
- DynamoDB is a serverless NoSQL database, ideal for key-value and document data models where a flexible schema is needed.
- On-Demand capacity is best for new or unpredictable workloads, charging per request, while Provisioned capacity is for predictable traffic and offers lower costs.
- Global Tables provide a multi-region, active-active database for low-latency access for a geographically distributed user base.
- DAX (DynamoDB Accelerator) is an in-memory cache that dramatically speeds up read performance for read-heavy applications.
- A common exam trap is choosing DynamoDB for scenarios requiring complex SQL joins, which is a feature of relational databases like RDS.
