Is there a way to force "depth-first execution"? Like, "only process 4 chunks at a time" or something like that? I have a Flow where I'm downloading a bunch of files, uploading them them to a Snowflake stage, and then deleting the folders. Right now it tries to download everything and I think it's blowing up the container's storage. Is there a way to make it go "down" before going out (thus clearing disk space), or maybe just be generally smarter about disk space? Thanks!
