Guys, We have a capacity planning page  in docs, but it's not very easy to follow this guide when data is loaded from a large database with 100s of tables. How about we add this calculation to the Web Console? I think we can do this during the model import - get the counts of each table and approximate the size of each table's row.
Alexey K, is this doable?  http://apacheignite.gridgain.org/v1.7/docs/capacity-planning -Val
