Class MongoDBDialect

java.lang.Object
  org.hibernate.ogm.dialect.mongodb.MongoDBDialect

All Implemented Interfaces:

Serializable, GridDialect, org.hibernate.service.Service

public class MongoDBDialect
extends Object
implements GridDialect

Each Tuple entry is stored as a property in a MongoDB document. Each association is stored in an association document containing three properties: - the association table name (optionally) - the RowKey column names and values - the tuples as an array of elements Associations can be stored as: - one MongoDB collection per association class. The collection name is prefixed. - one MongoDB collection for all associations (the association table name property in then used) - embed the collection info in the owning entity document is planned but not supported at the moment (OGM-177) Collection of embeddable are stored within the owning entity document under the unqualified collection role
