Exploring indexes in Azure Cosmos DB

Azure Cosmos DB is a distributed database service with high scalability, low latency, and global distribution. It is designed to be used with modern, cloud-based applications that require fast, responsive data access and the ability to scale to meet changing demands. One of Cosmos DB’s key features is its indexing support, which allows data to be queried and retrieved more efficiently.
