How to copy objects in single transaction in S3

Question

Is it possible to copy a list of objects or sub-directories in a directory in S3 to another directory in a single transaction?

I need this in java

Answer 1

No, this isn't possible. Individual writes (object creation and copy) are atomic -- they either succeed or they don't -- but S3 is not transactional. Each copy operation is for a single object, so copying multiple objects requires multiple operations, and each one succeeds or fails independently of the others.
