I already know that in the datastore there is no aggregation functions, and i also know about the 1000 entites fetch limit in a query.
But I would like to know how did you solve this problem. My application allows to webmasters to charge to their users by sending sms to access to their contents. Every webmaster can have many sites and every website can have many contents. So I would like to display some reports, for example: 1) how many sms did receive dayly from one date to another for every site and for one site in especific. 2) how many sms did receive from 0hs to 24hs for a especific date for every site and for one site in especific. 3) how many sms did receive from each country from one date to another date. 4) how many money did receive dayly from one date to another for every site and for one site in especific. 5) how many money did receive from 0hs to 24hs for a especific date for every site and for one site in especific. 6) how many money did receive from each country from one date to another date. 7) the same reports to the root user aggregating by webmaster / site / content and grouping by date, hour, etc. etc etc etc Do I need to create counters for every report that i need? Let's say that i do this, and in one month i think that could be nice to display another report and i dont have the counter for this, for example, how many sms the webmaster receive by minute. Here, what can i do? -- You received this message because you are subscribed to the Google Groups "Google App Engine" group. To post to this group, send email to [email protected].
