The processors were written by different developers, at different times, with different use cases in mind. The end result is different approaches to creating storage service client objects and managing credentials. Although the current S3 processors are not designed with per-flowfile expressions in mind, it would be possible to modify them to follow a pattern more like the Azure Blob processors.
