Re Building an Event Storage (2)

[dokie]

Good and simple explanation of the most basic needs of the event
store. The idea outlined about using Memento over default
serialization is a good call.

I particulary like the further micro-optimization of the Publisher
idea at the end also as it still plays nicely with the overall "append
only" and read up to model of the store which we have worked hard to
get by the overall CQRS approach.

Excellent explanation, thank you very much for the material.

I have 2 observations so far:

- why not use the sequenceNumber as the version? This way, you only
have to store / manage a single number. Unless having numbers in
sequence is important for the version?
- the snapshots principle could also be used when moving from a
state based system to a event sourced one. One could migrate existing
aggregates into snapshots and start event sourcing from there.
