This guide describes the steps to configure Tableau for using it with the Qubole Data Service.
To define the connectivity between Tableau and Qubole, you must specify the Qubole API Token (which Qubole uses to authenticate access), the cluster name (cluster Label) and the endpoint (Qubole platform in the cloud provider where the customer has its Qubole account). The first time a query, a dashboard or a report is run, Qubole authenticates the Tableau user and starts the big data engine (Presto or Hive) that Tableau requires, if it is not already running. After that, Tableau sends SQL commands through the ODBC/JDBC driver that Qubole passes to the right cluster. Qubole manages and runs the cluster with the right number of nodes and only for the required time, thus saving users up to 40% in infrastructure cost
