    Hi Prashant
    
    I found the problem to upload large files via API was that it doesn't
    support streaming uploads.
    
    This has been fixed here:
    https://github.com/ckan/ckanapi/pull/109
    
    Works well for me. Also maybe you want to have a look at a client which
    makes use of that:

    Cheers
