I’m trying understand CQRS to see if it can help out in an reporting environment.

Problem: An CQRS designed system is already in production, happily generating commands, events and updating the necessary query views. A new report is required. This report takes a number of parameters; Start Date, End Date, Product Type, and Product Category.

How do I generate the aggregate views for:

  • A query store that will initially be empty
  • And, can pass parameters with very different values

Do I try and solve this using a CQRS approach, or is there a better alternative?

Thanks

    If it is not reasonable to precompute all your report data into flat view, then just don’t do that. You may want to join a bunch of tables for your report. It’s your decision what can be precomputed, and what is not worth it (cpu, storage considerations).

    In your particular case (StartDate, EndDate,..) – i can’t see what is the problem to generate a single ViewModel table for it, and just query directly against the parameters.
