event-sourcing

I'm reading up on event sourcing and have a question regarding persistence.

I can still have a DB with all entities, right? Or should the events be replayed every time the application is started to get the latest version of each entity in the memory? Seems like a waste on larger systems (as in large amount of data)?

The point with event sourcing is that I can can replay the events to populate a data store if required? (or analyze the data)

How do you stay backward compatible with event-sourcing? Let say you release a version that has one kind of event, let call it X. You know how to handle that event in all the systems that extracts the events from the event source. In a later release you make a change to event X or delete it, how do… >>> More

Before being rebranded as Event Sourcing, this type of architectural pattern was known as System Prevalence but yet I was never familiar with this pattern… >>> More
How do you end up with event-sourcing if you use a xDD approach?

When working in a TDD or BDD manner your unit tests are supposed to drive your design. But how do you end up with event-sourcing using a xDD techniques? As I see it event sourcing is something you need to adopt early on to take full advantage of it. Lets say that you start without event-sourcing… >>> More
