CQRS

In regular client-server development, the server is responsible for providing the client with all CRUD (create, read, update, and delete) capabilities. However, when users look at data they do not often require it to be up to date to the second (given that they often look at the same screen for several seconds to minutes at a time). As such, retrieving data from the same table as that being used for highly consistent transaction processing creates contention resulting in poor performance for all CRUD actions under higher load.

Querying: - Have a look to Users, what are they really interested in? - It's not searching, it's finding; - It's not refreshing, it's looking for events
