Hi All,

The method that Udara mentioned would indeed improve performance. but when
we scale it up to couple hundred or more applications again this will
become a overhead. So how about introducing a map ( as an cache ) that
keeps all the invocation data until the map is written to the database
periodically.This way all the counter data in the map can be added to the
database in a single batch operation which would scale even if there is a
large number of applications.

Best Regards,
Pulasthi

I have implemented a Javascript to store the events and post periodically.
When an user clicks on an App, javascript triggers and store the relevant
data(AppId, UserId) as events(in client side) and periodically (user can
define the time gap) JS posts the event[] to a jaggery file. Then from the
jaggery it sends the data to server.
