AmazonS3 putObject with InputStream length example

Question

I am uploading a file to S3 using Java - this is what I got so far:

AmazonS3 s3 = new AmazonS3Client(new BasicAWSCredentials(\"XX\",\"YY\"));

List

        

Answer 1

I've created a library that uses multipart uploads in the background to avoid buffering everything in memory and also doesn't write to disk: https://github.com/alexmojaki/s3-stream-upload

Answer 2

Just passing the file object to the putobject method worked for me. If you are getting a stream, try writing it to a temp file before passing it on to S3.

amazonS3.putObject(bucketName, id,fileObject);

I am using Aws SDK v1.11.414
