27 which will be deliberately obscured from logging.

37 Indicates that a subworkflow should run in a single container
38 and not be scheduled as separate steps.

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

86 Size of file data buffer for Keep mount in MiB. Default is 256
87 MiB. Increase this to reduce cache thrashing in situations such as
88 accessing multiple large (64+ MiB) files at the same time, or
89 performing random access on a large file.

135 Specify desired handling of intermediate output collections.
139 doc: "Always 'arv:IntermediateOutput'"
146 If the value is greater than zero, consider intermediate output
147 collections to be temporary and should be automatically
148 trashed. Temporary collections will be trashed `outputTTL` seconds
149 after creation. A value of zero means intermediate output should be
150 retained indefinitely (this is the default behavior).
152 Note: arvados-cwl-runner currently does not take workflow dependencies
153 into account when setting the TTL on an intermediate output
154 collection. If the TTL is too short, it is possible for a collection to
155 be trashed before downstream steps that consume it are started. The
156 recommended minimum value for TTL is the expected duration of the
