    Is it necessary to ingest data into Tableau in order to be viewed or can Tableau connect directly to a data source

    Chris Hayes

      I have not used Tableau, but had a look at Qlikview, which I assumed to be similar.  With Qlikview, you have to import the data into an RDBMS, put it into some particular form for loading into memory, then load it into memory in order to view it.   Is this the case with Tableau?

       

      I have seen claims that infer that you can connect Tableau directly at 'big data' like a Hadoop file system, but I"m not sure, and I want to know what processing this requires, .  In the case of HFS, does this require construcing HiveQL queries or using Impala?
