    Slow Performance when connected tableau to spark sql server on gcloud.

    Abhishek Kumar

      Hello Everyone, I'm trying to make a report from very large data (more than 40lakh rows)using spark-sql ,which  is on gcloud but tableau is taking a very long time in executing the query and computing the visualization and also I have added one more connection in the report for adding one more tableau because join is very heavy task.When I see the yarn manager it shows that query is already finished executing long time but tableau is still executing the query.And when I switches between the dashboards it again ask for reconnecting. Please if any one can give suggestions for its optimization and getting fast result.Plus I want to publish this report so what will be better for publishing/viewing (tableau server,online,viewer or reader) the live connection reports without taking much time .
