Hello, Suppose i have a kind named Employee with millions of tuples stored in GAE. The Employee kind has properties/attributes like EmployeeId, EmployeeName, Salary, StartDate, DepartmentId.
I would like to know the selectivity of each properties/attributes. In order to do that, i want an very efficient way to know for example the lowest, highest salary in Employee kind, number of different EmployeeName in Employee kind. Do you have any suggestion?
