Get an S3Object InputStream from a GetObjectResponse in AWS Java SDK 2 Using S3AsyncClient?

Question

How can a plain InputStream be created using the S3AsyncClient for a getObject request?

The S3AsyncClient for AWS JDK 2.0 does not seem to have a function that returns a ResponseInputStream<GetObjectResponse> the same way that the S3Client synchronous client does.

The only return type available is a CompletableFuture<GetObjectResponse>, but the methods returning that type assume that the data is going to a local path.

S3AsyncClient s3AsyncClient = ...;


CompletableFuture<GetObjectResponse> response = s3AsyncClient.getObject(
    GetObjectRequest.builder()
            .bucket(bucket)
            .key(key)
            .build(),
    path));    

There is a similar stackoverflow item, but the question and answer both utilize the synchronous S3Client.

Thank you in advance for your consideration and response.

Below code would get you the InputStream.

ResponseInputStream responseInputStream = s3AsyncClient.getObject(GetObjectRequest.builder()
        .bucket(bucket)
        .key(key)
        .build(),
        AsyncResponseTransformer.toBlockingInputStream())
