CONSISTENCY PATTERNS

A system design tutorial on 3 consistency patterns used in distributed systems. Strong consistency ensures that all servers always retrieve the latest data, but it can reduce service availability and increase latency. Eventual consistency, which favors high availability and performance over consistency, ensures that the system will eventually converge to the same state, but it may return stale data in the interim. Weak consistency, which prioritizes high availability and low latency, may or may not return the latest data. The choice of consistency pattern depends on the system requirements and use cases.

This reduction not only means less code to download and store, but also improves startup time as less source code needs to be scanned before the JavaScript is run. This is a great read on how the VSCode team identified the technical problem and how they arrived at the solution.
