The ability to change a published datasource from a Live Connection to an Extract is not currently built into Tableau Server. If you would like to make this change, the datasource will need to be republished from Tableau Desktop. When you say it cannot be extracted by Tableau Desktop because it contains huge records, are you receiving an error when attempting to save the extract?
Thanks and hope this helps!
Thank you for your reply.
I understand the ability is not ready current version of Tableau Server(Include Tableau Online).
Honestly I have never completed extract on my target datasource.
Tableau Desktop display a dialog for a message "importing data" over several hours.
I have always canceled the process by myself because I have to shut down my PC when I leave the office.
I might concur with justin about publishing empty extracts and populating em. You might be working with a large data set...
Thank you for providing interesting information.
I prepared empty extracted that made according the URL you gave, and published it .
I am looking forward to confirming the result of extract!!
That is a cool article! I had never seen work-around before. Russell really knows his stuff!
