Explaining containers in Azure Cosmos DB

Containers in Azure Cosmos DB serve as logical partitions for storing data, but they differ significantly from tables in a relational database. While a table in a relational database enforces a uniform structure for all records, a container in Azure Cosmos DB allows for more flexibility. The shared aspect across documents in a container is the partition key, which determines data distribution for scalability. Unlike relational databases, where strict schema adherence is essential, Azure Cosmos DB encourages a more adaptable approach. It’s crucial to recognize that transitioning from relational concepts to NoSQL requires a fresh perspective to make informed choices and fully harness the benefits of this flexible data model.

Containers can store various data types, including documents, key-value pairs, column-family data, and graphs. Containers can also be partitioned across multiple physical nodes for improved scalability and performance...
