Question

A Node.js inspection service must persist a nested checklist object to DynamoDB without turning numbers into unexpected strings or dropping nested maps. What should the team use?

Accepted Answer

Use the AWS SDK document client (or equivalent marshalling) so native JSON maps, lists, and numbers map correctly to DynamoDB AttributeValue types — Hand DynamoDB a real nested object the way your app thinks about it. The document client (or proper marshalling) keeps numbers as numbers and maps as maps—no surprise string conversions.

Answer

Store the checklist only as a CSV string in a single String attribute

Answer

Write each nested field as a separate MySQL column through the RDS Data API

Answer

Base64-encode the object and store it as a Binary attribute without a schema
