Tableau data Extract Fails with Large Data source

I am using Tableau Desktop 8.2 with connection to Amazon Redshift creating an extract and publishing data source to tableau server is my task, but recently i'm encountering some issue like

"Data connection Lost Unable to create an Extract"

"Communication error while getting a tuple; Error fetching next row Unable to create extract"

We increased the number of cursors in Amazon Redshift

My concern is when say like 16 Million records are to be extracted and extraction goes till 8 Million and the above error occurs is it possible to get the Extract for last 8 Million Atleast ?

Every thing get rolled back after a Failure / error is it possible to prevent this what are my options?

You could also use the data extract API and have more control over the connection and error handling, at the cost of writing a modest C, Python or Java program
