Thanks a lot Eli for sharing your thoughts on this. So what you are suggesting is that I can do with just List<key> communitiesJoined in User class.
I need not have a mapping of users enrolled in community in Community class. And whenever i need to retrieve the list of users in a community, I should do select query with like Select * from Users where communityId in List of communities. Ain't this going to impact the response time to a greater extent? I think there has to be a trade-off between memory utilization and response time depending on the requirement. Is there some research done on which will be faster or some sample application which can show us which technique will be better. -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
