Introduction

Welcome to Day 8 of our "254-Day Hands-On System Design" journey! Last week, we built a simple local log processing pipeline. Today, we're taking a big step forward by implementing a TCP server that can receive logs over the network. This is crucial for any distributed system because it allows us to collect data from multiple sources across different machines.

By the end of today, you'll have a working TCP server that accepts connections and receives log data from remote clients. This is a fundamental building block in modern distributed systems used by companies like Netflix, Uber, and Spotify to process millions of logs every second.
