System Level and Functional Requirements for the Backend Database of a User Engagement Platform
Very good and practical analysis of what the requriments of a user engagement platform are for the backend database from both the system level and functional point of views. The ideal case is also spelled out, but I don’t think there’s one product out there that could do all of these:
So, today’s and tomorrow’s engagement services should accommodate, heavy write loads, heavy read loads, heavy aggregate(counter), modify and read loads. What becomes apparent if we look at user engagement services in this way is that aggregation needs to be a first class function of engagement services that is near real time, scalable and highly available.
