Question 1

How does AWS Elixir compare to ExAws for Elixir?

Accepted Answer

AWS Elixir is generated from official AWS models, offering accurate and up-to-date service coverage, while ExAws provides more hand-crafted features and community-driven convenience wrappers. Choose AWS Elixir for raw API fidelity; ExAws for higher-level abstractions.

Question 2

How to upload a file to S3 using AWS Elixir?

Accepted Answer

Use the AWS.S3.put_object function with a client, bucket, key, and a map containing the file body and optional attributes like ContentMD5, as demonstrated in the README example for integrity checks. Remember to set ContentType manually if needed.

Question 3

Does AWS Elixir support S3 multipart uploads for large files?

Accepted Answer

Yes, it supports multipart uploads through functions like create_multipart_upload and upload_part, with examples in the README showing how to handle chunking and completion to avoid timeouts for big files.

Question 4

Is AWS Elixir officially supported by Amazon?

Accepted Answer

No, it's an open-source project maintained by the aws-beam community, not an official AWS SDK. However, it leverages AWS's official service models for generation, ensuring reliability.

Question 5

How to handle errors in AWS Elixir API calls?

Accepted Answer

Functions typically return tuples like {:ok, result, resp} or error patterns; check the response for status codes and error details based on integrated AWS documentation. The library doesn't provide custom error types beyond AWS's raw responses.

Question 6

Can I use a custom HTTP client instead of hackney with AWS Elixir?

Accepted Answer

Yes, you can implement a custom HTTP client by configuring the AWS.Client module, as mentioned in the Installation section. The library is designed to be flexible, allowing overrides of the default hackney client.
