Hi, I am saving information regarding the users of my gadget. I have a procedure where I need to get information about the user friends who are also using my gadget. a. Is there a best practice for this issue?
b. I want to aggregate the data, I've read about the counting methods in BigTable, but they seem to work for data that you know from the start.. In case of user friends, it can vary on a daily basis, as well as totally dynamic (I currently retrieve the friends list via the python-client project in Google code)... How can this be done, without iterating through the list and fetching the user entities from the datastore (and even if that's the only way, won't this fetching cause bad performance? c.How common is the use of ListRefrence in BigTable, and is it known to be good? I have a DB model who has only 20 entities... But I like the back reference it creates for me (Instead of implementing a counter for each entity) But after digging and reading about the uses of BigTables I think that the more references you have, less performance you get... Please help, Chen. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Google App Engine" group.
