S3TransferManager dont have an option to override http configuration

[karthiknaren]

Hi @zoewangg ,

We are trying to use S3AsyncClient.crtBuilder but don't have an option to override Httpclient .
Could you please suggest.

Is it possible to have the override S3 Httpclient configuration.

@karthiknaren I don't quite understand the question. Which HTTP client would you like to provide?

You can use S3AsyncClient.crtBuilder() to configure a custom CRT-based client (which is an async HTTP client) and then provide this client to the S3TransferManager. Here's an example from the Developer Guide:

    S3AsyncClient s3AsyncClient = S3AsyncClient.crtBuilder()
                .credentialsProvider(DefaultCredentialsProvider.create())
                .region(Region.US_EAST_1)
                .targetThroughputInGbps(20.0)
                .minimumPartSizeInBytes(8 * MB)
                .build();

    S3TransferManager transferManager = S3TransferManager.builder()
                .s3Client(s3AsyncClient)
                .build();

You can find more examples in the Amazon S3 Transfer Manager Guide -

@debora-ito ,
Is there a way to override proxy host.
In S3AsyncClient.builder().httpClient(null) we have a method to override proxies.
but in S3AsyncClient.crtBuilder() not have an option to override proxy
Could you please suggest.

S3TransferManager does not support proxy settings currently, we are tracking the feature request here: #3262

Environment variables like HTTP_PROXY and HTTPS_PROXY are supported (but NO_PROXY isn't).
