Hi Allard,
Almost 6 years ago I participated in some application which collects date (fuel level, gps coordinates ant etc) from fuel tanker trucks thru wireless network.
We never heard about CQRS at this time but architecture was very similar, we collect chain of event for each truck (honestly we don’t save difference between events but actual values).
However we provide only 6 months data life cycle support to customers (capacity/performance issue at this time). Actually aggregate almost will be never closed (deleted) but data does.
So, just want to share some real business case where we still need actually to delete aggregates or their data.
Thanks,
Evgeny Kochnev
