I can't find a place to ask questions about Amplify and its storage API, so here goes:

• Do you support S3 transfer acceleration?
• Do you have any simple Lambda upload examples where credentials are assumed from the lambda role? Or is a Cognito configuration always required?
• Do you support direct client side uploads to S3 from a browser?
• Can you handle large videos when uploading?

Hi @kaihendry

Do you support S3 transfer acceleration?

It is currently not supported. Amplify leverages the aws-sdk-js package and that one supports it, so it should be doable in Amplify

Do you have any simple Lambda upload examples where credentials are assumed from the lambda role? Or is a Cognito configuration always required?

Do you support direct client side uploads to S3 from a browser?

Yes, this is currently supported in Amplify. Take a look at this repo with a sample app that does that using amplify https://github.com/aws-samples/aws-amplify-graphql

Can you handle large videos when uploading?

Currently, for files bigger than 5mb, the underlying aws-sdk-js uses multipart upload

Thank you for answering my questions!

Does multipart upload work from the client side browser? Can it for example resume?

It looks like there's an issue with multipart upload on the client side.
The second part is cancelled when the first part response...
Since the second part got cancelled, a delete request is then sent out.

Would very much interested in knowing a workaround for this issue

We have a feature-request for better multi-part upload support, tracking on:
