+ local_output_dir: Use regular file system local to the compute node.
+ There must be sufficient local scratch space to store entire output;
+ specify this with `outdirMin` of `ResourceRequirement`. Files are
+ batch uploaded to Keep when the process completes. Most compatible, but
+ upload step can be time consuming for very large files.
+ - |
+ keep_output_dir: Use writable Keep mount. Files are streamed to Keep as
+ they are written. Does not consume local scratch space, but does consume
+ RAM for output buffers (up to 192 MiB per file simultaneously open for
+ writing.) Best suited to processes which produce sequential output of
+ large files (non-sequential writes may produced fragmented file
+ manifests). Supports regular files and directories, does not support
+ special files such as symlinks, hard links, named pipes, named sockets,
+ or device nodes.

+ Size of file data buffer for Keep mount in MiB. Default is 256
