I can supply a mapd’s JDBC driver that works with JDBC generic data sources of Tableau, but you need at least 2018.3 release (never tried in 2018.3 but it should work, it is working on 2019.1 betas)
It’s far from perfect because it’s not extensively tested.
you can download the driver from here
to use the driver you have to place the jar file on drivers directory of your tableau installation (something like c:\program files\tableau\drivers), then select other databases (JDBC) as server connection and type in the appropriate url and specify SQL 92 as a dialect
If you will face any problem using the driver, please report back, and I’ll fix asap.
there is a known problem on Week Number with jdbc generic sources with sql92, but it’s a Tableau problem that it has been already reported to the support, so I hope it will be corrected asap.
The jdbc driver of mapd doesn’t work with tableau out of the box; I’ll do a pull request soon to include modifications needed to make the driver works, with tableau and microstrategy.
The biggest problem is the support for those datasources in Tableau is recent, so they are doing modifications on every beta step, so i have to wait for a stable release to be sure the driver is working.
