Stream - Event Sourcing

About

Instead of focussing on current state, you focus on the changes that have occurred over time. It is the practice of modelling your system as a sequence of events.

Event Sourcing domain expert won't talk about “tables” and “joins”, they'll describe processes as the series of events that can occur and the rules applied to them.

  • State of data is a stream of events
  • Eases auditing
  • Eventual Consistency
  • Distributable stream through a Message Bus

Example: Stream - How to capture change of state - Change Data Capture (CDC)
