What I have?
I have loaded roughly 20GBs of CSV file into Tableau Desktop to create some worksheets for future internal views.
What I want?
I am confused on what should I choose Extract or Live data source. The data itself will not change, only the reports or worksheets generated based on the data. The computations within the worksheets on Tableau Desktop take forever to complete.
On to the publishing to Tableau Server. I am under the assumption that I must upload my locally stored file to the server for future use. Would it be better to find a network drive to have the Tableau Server data source point to?
Additionally, I also want to know what Regex methodology does Tableau follow?
