I am working on a solution which i am trying to solve using CEP. I would need to understand what is the recommended pattern in CEP
to solve such problems. Would also request for some low level implementation details as i am new to this technology.
Here are the details
I have two streams e.g Stream A and Stream B
Stream A contains the list of trasactions (service usage transaction) by the customer and
Stream B contains the billing transactions for the usage.
Now there is a requirement to check if there are any service usage transaction (Present in Stream A) but missed the entry in the Billing Stream (Stream B).
The correlation between the Stream A and Stream B is Customer id and the Transaction Log Time( Same timestamp in both streams)
The Cardinaity between two stream is one to one.
