What's the best way to trigger DynamoDB Import from S3 in Step Function?

Question

I can't see a support of [DynamoDB Import from S3](https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/S3DataImport.HowItWorks.html) among the out of the box integrations in [Step Functions](https://docs.aws.amazon.com/step-functions/latest/dg/connect-ddb.html).

Is there a way to trigger it somehow, other than having some Lambda that has aws-cli in it?

Accepted Answer

While it is not available from the `Optimised Integration` API's, all of the DynamoDB API's can be called from the `DynamoDB AWS SDK Integration`.

**How the optimized DynamoDB integration is different than the DynamoDB AWS SDK integration**

- There is no optimization for the Request Response integration pattern.
- The Wait for a Callback with the Task Token integration pattern is not supported.
- Only `GetItem`, `PutItem`, `UpdateItem`, and `DeleteItem` API actions are available through optimized integration. Other API actions, such as `CreateTable` or `ImportTable` are available using the DynamoDB AWS SDK integration.

Answer

I think I found the answer myself. Even though the import is not listed in the docs, it seems to be available in AWS Console:

![Import](/media/postImages/original/IM_Jg5UMbhSAy7IKBblRXDBw)

And it seems to use this API:
