Hi folks.

Thomas, I'm trying understand the h2 cost model and I'm having some doubts. Why 
do you multiply the costs to the level tree nodes? How you choosed the 
coeficients of  item access type (index and so on)? Is there any specific 
documentation to the  cost model? How do you choosed this cost model, have you 
based in another model? Do you have some plan to add other join methods or 
include CPU cost in the model? Do you use histogram to make some predictions?

Att,

Fred
