In this blog post we'll design a collaborative 2D table structure using yrs - Rust port of popular yjs conflict-free replicated data types library for creating real-time, local-first apps. We'll also cover some optimizations to improve…

Plumtree - epidemic broadcast trees
Some time ago, we covered an idea behind HyParView [https://bartoszsypytkowski.com/hyparview/], a cluster membership protocol that allowed for very fast and scalable cluster construction. It did so by using the concept of partial view: while our cluster could…
