Consensus Algorithms. What Does Node.js Have to Do with It?
summary
Explains consensus algorithms in distributed systems: the problems they solve (like consistency and coordination) and related concepts. Then examines an educational project that demonstrates what’s needed to implement a high-performance, linearizable key-value store in Node.js, discussing practical requirements and trade-offs.
