Autogenerate id in Cosmos DB from Spring Boot

Question

How can I generate an autoincremented Id in a Cosmos DB if I do a POST request from Spring Boot.

Answer 1

The docs explain the behavior here: https://github.com/Azure/azure-sdk-for-java/blob/main/sdk/spring/azure-spring-data-cosmos/README.md

public class GeneratedIdEntity {

    @Id
    @GeneratedValue
    private String id;
}

As mentioned, Cosmos uses UUIDs rather than an auto-increment long.

Answer 2

Use @Id @GeneratedValue private String id;
