Map Clojure data operations to DynamoDB item reads, writes, updates, deletes, and batch workflows.
This section bridges the chapter overview and the detailed lessons below. For Java engineers, the practical question is how to handle DynamoDB item and batch operations in Clojure code at the database boundary.
| Review focus | What to check |
|---|---|
| Item shape | Keep Clojure maps aligned with DynamoDB attribute expectations. |
| Batch limits | Design retries and partial failures deliberately. |
| Side effects | Separate pure item preparation from AWS calls. |
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.
