Today we'll continue a series about CRDTs, this time however we'll stray from the path of state-based CRDTs and start talking about their operation-based relatives. The major difference that we need to cover, is the center of gravity of this…

Hybrid Logical Clocks
In this blog post we'll going to talk about timestamps. But to start with we need to answer the basic question: what are we using timestamps for? Two most common cases are: 1. We want to timestamp our records so…
Make your cluster SWIM
In this blog post we'll cover how systems form clusters, what clusters actually are and what are their responsibilities. We'll also present different protocols responsible to serve the needs of the clusters with a various tradeoffs associated with them. To…
State-based CRDTs: Maps
In this blog post, we'll cover the idea of CRDT maps, and how we could create them and utilize them in common scenarios. A prerequisite for this talk is some general knowledge of CRDTs, especially observed-remove sets [https://www.bartoszsypytkowski.…
State-based CRDTs: Bounded Counter
Originally, I didn't want to make a separate blog post about design behind bounded counters, but since beside original paper [https://pages.lip6.fr/syncfree/attachments/article/59/boundedCounter-white-paper.pdf] and a very few implementation living in the wild, this…
