The Library Inventory System

Every module from here on either builds a piece of this system or hardens a piece you already built. Get the shape of it into your head now, and every later "why are we doing this" question answers itself.

Learning objectives

  • Beginner: Describe the Library Inventory System's producer/consumer split in one sentence.
  • Intermediate: Explain why the system uses two separate microservices instead of one, tied to Kafka as the connecting layer.
  • Advanced: Anticipate which later module hardens which specific piece of this architecture, before being told.
