A well-configured development environment makes everything easier — faster iteration, reliable testing, and fewer surprises in production.
Sajeetharan Sinnathurai (Principal PM, Azure Cosmos DB) walks through setting up a complete Azure Cosmos DB development workflow, then shows how to supercharge it with AI coding assistants:
• VS Code configuration and essential extensions for Cosmos DB
• Local development with the Cosmos DB emulator (limitations and cloud switching)
• Testing patterns, integration tests, and CI/CD considerations
• Using context files to teach AI assistants your schema
• Effective prompting for better Cosmos DB queries, SDK code, and data models
You’ll leave with a ready-to-use setup, sample context files, and a repeatable workflow that accelerates Cosmos DB development.
