Consistency

The two generals problem and the impossibility of consensus

The two generals problem and the impossibility of consensus

Savvas Kleanthous
This is the second blog post in a short series about Consistency I love the two generals problem. I am mesmerized by its simplicity and impossibility. And I believe nothing has shaped my professional life more than this problem. Back in 2008 I had not yet worked with any major distributed systems, and most of my work was with systems which involved heavy aspects of custom electronics; one could say I was into IoT before IoT was a thing.

A primer and a rant about eventual consistency

This is the first blog in a short series about Consistency When I decided to start my blog again, I created a poll about what should I write first. The reason was that I have gathered material about 2-3 subjects which I liked and wanted to speak about, but I wasn’t sure which one to start with. More people voted than I expected, but the decision was a tie between what different types of events would be helpful to recognise in an Event Sourced system, and Distributed consistency.
