• to define the command line arguments to specify storage clases
• to have all the expected behaviour for arv-put
• to add to the documentation this behaviour
• to add necesary tests to make sure we comply with this behaviour

• shall we migrate arv-put to Go in this instance or is this a future work?

Current command line arguments (arvados 2.1.0) :¶

arv-put --help 
usage: arv-put [-h] [--version] [--normalize | --dry-run]
               [--as-stream | --stream | --as-manifest | --in-manifest | --manifest | --as-raw | --raw]
               [--update-collection UUID] [--use-filename FILENAME]
               [--filename FILENAME] [--portable-data-hash] [--replication N]
               [--storage-classes STORAGE_CLASSES] [--threads N]
               [--exclude PATTERN] [--follow-links | --no-follow-links]
               [--trash-at YYYY-MM-DDTHH:MM | --trash-after DAYS]
               [--project-uuid UUID] [--name NAME]
               [--progress | --no-progress | --batch-progress] [--silent]
               [--resume | --no-resume] [--cache | --no-cache]
               [--retries RETRIES]
               [path [path ...]]
(..)
  --replication N       Set the replication level for the new collection: how
                        many different physical storage devices (e.g., disks)
                        should have a copy of each data block. Default is to
                        use the server-provided default (if any) or 2.
  --storage-classes STORAGE_CLASSES
                        Specify comma separated list of storage classes to be
                        used when saving data to Keep.

base casecase¶

arv-put --replication N  --storage-classes STORAGE_CLASSES directory

Expected behaviour: ...

updating an existing collection¶

arv-put --replication N  --storage-classes STORAGE_CLASSES directory --update-collection zzzzz-4zz18-xxxxxxxxxxxxxxx

Expected behaviour: ...

giving conflicting options for resume transaction¶

arv-put --replication N  --storage-classes STORAGE_CLASSES directory
arv-put --replication M  --storage-classes DIFFERENT_STORAGE_CLASSES directory --resume

Expected behaviour: ...
