Tableau data instances don't work with large data source
I am using Tableau Desktop 8.2
with connect to Amazon Redshift
, creating fetch and publish datasource on tableau server, this is my task, but lately I am facing some problem like
"Data connection Lost Unable to create an Extract"
"Communication error while getting a tuple;
Error fetching next row
Unable to create extract"
We have increased the number of cursors in Amazon Redshift
My concern is that say 16 million records have to be extracted and mining continues to 8 million, and the above error occurs if you can get Extract for the last 8 million atleast?
Every thing is rolled back after a Failure / error, to prevent this, what are my options?
