Hi,
I have the following class.
GlAccount {
@Id Long id;
String customerid;
Date date;
double balance;
}Here, I am querying by date and customerid. If I get back an existing entity, I update the new balance and do put of the entity If not, I create a new GlAccount (Date, balance, customerid), and do put(). If I have a large number of customers say, 100000, and if I want to store the customers balance by each date, then the records are growing by 100000 every day. Now, I do not want to use this, instead I am thinking of using the listproperty to add the Dates. I watched in the video 'Google I/O 2009, scalable, complex apps' by Bred Slatkin, that a listproperty has several advantages, and can also be used for tuples. Any suggestions, on how this listproperty can be used, so that I can query for the balance for a given date and customerid. -Aswath -- You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.
