Plan DynamoDB table keys, capacity modes, and throughput expectations before Clojure services depend on them.
This section bridges the chapter overview and the detailed lessons below. For Java engineers, the practical question is how to handle DynamoDB table and capacity planning in Clojure code at the database boundary.
| Review focus | What to check |
|---|---|
| Keys | Choose access-pattern-driven partition and sort keys. |
| Capacity mode | Match provisioned or on-demand capacity to traffic shape. |
| Failure modes | Surface throttling and retry behavior at the service boundary. |
Use the child lessons to move from concept to implementation. The section goal is to make the trade-off visible before the code hardens around a database assumption.
