Is there any annotation for creating indexes in Cosmos document?

June 22, 2022

In JPA we can create indexes for the entity using annotations like –
@Table(indexes = @Index(columnList = "firstName"))

Do we have a similar way of creating indexes for the Cosmos DB?

>Solution :

With Spring data cosmos, you can define custom indexing policy using @CosmosIndexingPolicy annotation for your container.

Example:

@Container(containerName = "users")
@CosmosIndexingPolicy(
        includePaths = {
                "/name/?"
        },
        excludePaths = {
                "/*"
        }
)
public class UserDocument {
    @Id
    @GeneratedValue
    @PartitionKey
    private String id;

    private String name;
}
