PowerBI + HP Vertica questions

$

Hi all,

 

I'm currently working for a client trying to figure out if a switch from their current BI tool to PowerBI is relevant. Their analytics database runs on-premise with HP Vertica.

 

I understand that a build-in connector in PBI is not yet on the table for the dev team. On the other end, HP provides a step-by-step method to connect, which is what I will try next.

 

Is anyone knowledgeable on the matter ? Specifically :

  1. How long does it take to create the connection? Is there a way to mass install across many computers?
  2. Is it stable? Does it affect the available features of PowerBI in any way?
  3. My understanding is that the tables are downloaded and the model recreated when using the desktop version; the calculations are thus done on one's computer. When uploaded online on the Pro version, are the calculations (both PowerQuery steps and PowerPivot measures) done on an Azure-located Vertipack or converted into SQL and fed through Vertica?
  4. Is the performance of this connection good? Two aspects : A/ the client would be transitionning from SQL calculations on 30+ millions flat tables to a tabular model. I expect this is going to improve things quite a bit. Is there any reason why it wouldn't? B/ Performance of the proposed connection vs native PowerBI connections. Given the result of question 3, should I expect some trouble there?

 

Those would be my main concerns at this stage. I've had a first few very interesting talks with people a few days ago during a big data convention, but i'd like to know what's the word on this.

 

Best,

Antoine
