Does DynamoDB support GraphQL?

Yes, through AWS AppSync. AppSync is AWS's managed GraphQL service, and DynamoDB is one of its native data sources: resolvers map each GraphQL query or mutation to a DynamoDB operation such as GetItem, Query, or PutItem. DynamoDB itself has no GraphQL endpoint — the GraphQL layer runs in front of it.

How the pairing works

In AppSync you register a DynamoDB table as a data source, then attach a resolver to each field of your GraphQL schema. The resolver's request handler translates the incoming GraphQL arguments into a DynamoDB call, and its response handler shapes the item(s) DynamoDB returns back into the GraphQL response. AWS lists AppSync first among DynamoDB's serverless integrations for exactly this pattern.

Why it's a common stack

Both halves are serverless: AppSync scales the API layer while DynamoDB scales storage and throughput, with no servers on either side. Real-time GraphQL subscriptions pair naturally with DynamoDB's single-digit-millisecond writes.

The alternative: bring your own server

Nothing requires AppSync — any GraphQL server (Apollo, Yoga, and others) can resolve fields by calling DynamoDB through the AWS SDK, exactly as it would call any other backend. The trade-off is that you operate the GraphQL layer yourself.

Go deeper

GraphQL resolvers still hit the same access-pattern rules — the data modeling guide explains how to design keys that serve your queries, the expression builder generates the underlying condition syntax, and DynoTable lets you inspect what your resolvers actually wrote.
