             Summary: Ideas for better way to deal with arbitrary output files than ARCHIVE
                 Key: AIRAVATA-2741
             Project: Airavata
          Issue Type: Improvement
            Reporter: Marcus Christie
            Assignee: Marcus Christie

Just want to capture some details of recent conversations with [~eroma_a] and [~spamidig]
on how to improve Airavata capabilities so we can move beyond using ARCHIVE.  The ARCHIVE
capability is a bit of a hack and causes some issues for us. Just briefly, here are some of
the problems:
* pulls back absolutely every file but some aren't needed and some intermediate files are
very large. For some applications it isn't even practical to use ARCHIVE
* pulls back duplicates of Application Output files, further filling gateway data storage
* these files are basically opaque to Airavata, so there is a limit on what can be done in
a programmatic way for some of these files

Here are some potential improvements:
* improve wildcard support: allow specifying a wildcard that can match a single or multiple
files. For multiple files these can all be registered as a URI_COLLECTION type data output.
* Show all of the job files in the portal, including ones that aren't defined as Application
Outputs and haven't actually been staged back to the portal, and allow the user to request
pulling back one of these other files. This would be nice because there are certainly going
to be cases where a file is generated that wasn't anticipated (either lack of configuration
or just something truly not anticipatable). Would mean needing to register every file in the
job directory, not just the Application Outputs (not sure where, replica catalog?). Would
also mean we need backend task execution support for fetching these files as needed.
