[DRMAA-WG] What information should JobInfo provide ?

[Bruno P. Kinoshita]

I think can't contribute much in this discussion. In my case we store the job ID returned by the API, and store the information we supplied + this job ID in a local datastore. 

The filtering is local, using the data returned periodically from the cluster (a thread running in background updating the tool queue). This way users will be able to filter for jobs (by name, queue, priority, etc) but most of the data is already in the tool. The most important information retrieved from the server for us is the job status.

So in my case I think that this issue is not a blocker, but depending on how users want to use the API this can be useful. Maybe it would be useful to have a 'slim' method that returns a lightweight structure, and another one that returns the complete info? 

My 0.02 cents too :)
Bruno

JobInfo intentionally contains nothing from the job template at the moment, which makes perfectly sense if you see it as a pure reporting data structure. You don’t need to fetch information that you handed in by yourself as the calling application.
