Distributed Unique ID Generation

Overview

Design a sortable, collision-safe ID issuance path with centralized config and audit trail.

ID generation looks trivial until scale, ordering, and multi-region writes collide.

You will build 6 architecture steps that model production dependencies.

You will run 1 failure experiment to observe bottlenecks and recovery behavior.

Success target: IDs remain unique and near-time-ordered under concurrent multi-instance issuance.

Learning Objectives

• Can explain distributed ID design beyond UUID basics
• Can discuss worker allocation and clock assumptions
• Can defend audit strategy for uniqueness at scale

Prerequisites

• Topic Hub: Snowflake-style IDs
• Chapter 29: Unique IDs
• Prior Lab: Capacity Estimation Drill

Experiments

1. Throttle ID service instances and observe issuance bottleneck
