Core Concepts

This chapter explains the fundamental abstractions that make Zenoh unique.

Understanding these concepts will help you design systems that are:

• Location transparent — producers and consumers are fully decoupled
• Topology independent — your application logic doesn't change when you move from a single machine to a cloud-to-edge deployment
• Efficient — zero unnecessary copies, minimal wire overhead

Chapters

• Key Expressions — the naming system for all resources
• Sessions — the entry point to the Zenoh network
• Publishers & Subscribers — data in motion
• Queryables & Replies — data at rest and remote computation
• Storages — built-in persistence with location transparency
