Hi, Anshu! Please, don't forget to cc: maria-developers@ when discussing development topics. On Jun 18, Anshu Avinash wrote:

What I meant to say was we need N "linearly independent" equations to solve for N variables and that might not be the case. Some of the queries might not use any factor at all or use one factor more often.

Yes, you're right, of course.

Later we'll see what to do - perhaps we'll need to decrease the limit, or set it exactly to N (which means, the solution won't be "best fitting" anymore). But this will be not in this GSoC, not your project. I'm sure that in this project we won't have enough factors for memory usage to become an issue :)

Yes, I'll start with a basic least squares fitting model without caring much about the memory usage for now.

Sounds good. Regards, Sergei
