Hi,
I think it would be really nice i you could publish tableau data source directly out of the Discovery Hub.
The current process of deploy to .dsn file and then use tableau desktop to deploy it to the server is quite error prone and labor intense (which go against the whole idea of DH automation ;))
In my vision, Tableau server should be registered as endpoint and user should define deployment strategy (extract/live). click 'publish' and pray to God ;)
