Hi SamAdams,

How are you doing today?, As per my understanding, You're on the right track here! When you change the S3 path for Autoloader, even if the files are exactly the same and just copied from the old bucket, Autoloader will treat them as new files because it tracks them based on their original path and metadata. So yes, it could reprocess everything unless you take steps to avoid it. Setting cloudFiles.includeExistingFiles=False is a smart move—it tells Autoloader to ignore any existing files in the new path and only pick up new ones going forward. Adding {"pipelines.reset.allowed": "false"} also helps make sure the pipeline doesn’t accidentally reset and reprocess old data. As long as you keep your checkpoint location the same, and the old files don’t get picked up again, you should be safe. Let me know if you need help double-checking your setup before switching buckets!
