Azure Cosmos DB samples

One stop repo for all Azure Cosmos DB samples.

Overview

This repo contains code samples for Azure Cosmos DB for NoSQL organized by programming language. Each sample is self-contained and demonstrates a specific concept or operation using the Azure Cosmos DB SDK for each language.

Repository structure

Samples are organized by programming language at the root level. Each project is self-contained.

Numbering standard

Each sample folder is prefixed with a three-digit number that indicates its category:

Range	Category	Description
000–099	Connectivity	Basic connectivity, authentication, and client configuration
100–199	Quickstart	Hello-world style scenarios to get started quickly
200–299	Feature usage	Using specific Azure Cosmos DB features such as change feed or bulk operations
300–399	Patterns	Common application patterns and best practices
400–499	Advanced	Advanced scenarios including AI and vector search integrations
500–599	Vertical integration	End-to-end vertical integration scenarios

Validation

Every pull request and push to main runs the validation workflow, which enforces two things:

• Sample structure — all sample directories must follow the NNN-kebab-case-name naming convention (e.g. 001-quickstart) and include a README.md.
• Language correctness — changes under a language root folder (python/, javascript/, java/, dotnet/, go/) trigger the corresponding build and test job for that language only. Unmodified languages are skipped. One stop repo for all Azure Cosmos DB samples.
