Yeah obviously I meant 12.5 and just as an example, there could be more than 1000 customers. Some customers have small databases (less than 1 gig) and yet others are larger). The 1.25 multiplier was provided by QlikTech as a rough rule of thumb..
As for your suggestion to test for one customer, yeah we did. In fact, storing all customers in one combined file won't be a problem at all at first. However, it's best to be prepared for the future
I guess our situation is pretty uncommon. Thanks for the help.
You can setup so you have one master qvw to load data into, then distribute master qvw by loop and reduce to X amount of qvws, they will then run another loop and reduce and provide one specific document per user.
And you dont have to publisher master doc as each user has it´s own file. Or split it down to working sizes in the second step and then use Section access to control access, and publish DataAA,etc
