I have some experience with AWS S3 and lambdas but I was always working within one AWS account.
Now I want to copy a file (up to 2GB) from one S3 bucket belonging to AWS account A into other S3 bucket belonging to AWS account B. Account A is a partner account to which I have API access via accessKey and secret access key. Account B is my organization’s account to which I have admin rights.
Can I copy the file directly to my bucket? I mean without downloading the file to lambda instance and then uploading to my S3 bucket?
