+In "getting data from Keep,":tutorial-keep.html#arv-get we downloaded a file from Keep and did some computation with it (specifically, computing the MD5 hash of the complete file). While a straightforward way to accomplish a computational task, there are several obvious drawbacks to this approach:
* Large files require significant time to download.
* Very large files may exceed the scratch space of the local disk.
* We are only able to use the local CPU to process the file.
