Hi, Has anyone tried using Tableau on Spark SQL?
Specifically how does Tableau handle in-memory capabilities of Spark. As I understand Tableau uses its own propriety SQL against say Oracle. That is well established. So for each product Tableau will try to use its own version of SQL against that product like Spark or Hive. However, when I last tried Tableau on Hive, the mapping and performance was not that good in comparision with the same tables and data in Hive.. My approach has been to take Oracle 11.g sh schema <https://docs.oracle.com/cd/E18283_01/server.112/e10831/diagrams.htm>containing star schema and create and ingest the same tables and data into Hive tables. Then run Tableau against these tables and do the performance comparison. Given that Oracle is widely used with Tableau this test makes sense? Thanks.
