The modern way to build distributed systems 

Walmart, Netflix, Xero... just some names you've probably heard of that are harnessing the power of Event Sourcing: a pattern for storing data as events in an append-only log. 

But what does this mean for you as a Developer? Let's explore!

Go beyond current state data...

Ever wished you could travel back in time to see the previous state of your application?

Whether it's to make debugging easier or to fulfil a business request, with your Event Sourced application, you can do just that.

After all, Event Sourced applications don't overwrite past data; instead, it's all there when you need it. Rebuild state or even travel forward in time to understand the future behaviour of your system.

 

With Event Sourcing, you can basically store data/events/business decisions which you can re-use later on if you have new insights into the business and you can re-apply them. Pascal van Buijtene  |  Engineer, Event Store

Optimize both read & write models

Separating your read and write models means you can rest assured that your application is optimized for both. 

  • Escape the compromises of trying to have one system for both read and write models
  • Have multiple read models for different parts of your application
  • Easily add more read models as you need them, to help your system scale
My favourite thing about event sourcing is that it lets you separate the read and write sides, so you can optimize both rather than dealing with trade-offs. Tim Coleman  |  Distributed Systems Engineer, Event Store
