Serverless & Schemaless with Azure Functions and CosmosDB
summary
Demo shows C# code that receives checkout JSON via an HTTP endpoint, writes varied documents to Cosmos DB (using the Cosmos DB emulator locally), and a CosmosDB change feed trigger fires another Azure Function to handle shipping. Attributes and partition key are created automatically, a lease collection is provisioned, and the demo writes and reads two different record shapes successfully. Infrastructure auto-scales (scale controller example of 10 million messages) and everything runs end-to-end using Postman, local emulators and Azure Functions.
