Class RedisJsonDialect

java.lang.Object

org.hibernate.ogm.dialect.spi.BaseGridDialect

org.hibernate.ogm.dialect.impl.AbstractGroupingByEntityDialect

org.hibernate.ogm.datastore.redis.AbstractRedisDialect

org.hibernate.ogm.datastore.redis.RedisJsonDialect

All Implemented Interfaces:

Serializable, GroupingByEntityDialect, MultigetGridDialect, GridDialect, org.hibernate.service.Service

public class RedisJsonDialect
extends AbstractRedisDialect
implements MultigetGridDialect, GroupingByEntityDialect

Stores tuples and associations inside Redis as JSON.

Tuples are stored in Redis as a JSON serialization of a Entity object. Associations are stored in Redis obtained as a JSON serialization of a Association object either within the entity or external. See DocumentStoreProperties.ASSOCIATIONS_STORE on how to configure entity or external storage.

public GridType overrideType(org.hibernate.type.Type type)

Specified by:

overrideType in interface GridDialect

Overrides:

overrideType in class BaseGridDialect

getTuple

public Tuple getTuple(EntityKey key,
                      OperationContext operationContext)

Specified by:

getTuple in interface GridDialect

createTuple

public Tuple createTuple(EntityKey key,
                         OperationContext operationContext)

Specified by:

createTuple in interface GridDialect

executeGroupedChangesToEntity

public void executeGroupedChangesToEntity(GroupedChangesToEntityOperation groupedOperation)

Specified by:

executeGroupedChangesToEntity in class AbstractGroupingByEntityDialect

isStoredInEntityStructure

public boolean isStoredInEntityStructure(AssociationKeyMetadata keyMetadata,
                                         AssociationTypeContext associationTypeContext)

Specified by:

isStoredInEntityStructure in interface GridDialect

getAssociation

public Association getAssociation(AssociationKey key,
                                  AssociationContext associationContext)

Specified by:

getAssociation in interface GridDialect

createAssociation

public Association createAssociation(AssociationKey key,
                                     AssociationContext associationContext)

Specified by:

createAssociation in interface GridDialect

getAssociationRows

protected Object getAssociationRows(Association association,
                                    AssociationKey key,
                                    AssociationContext associationContext)

Returns the rows of the given association as to be stored in the database. Elements of the returned list are either

• plain values such as Strings, ints etc. in case there is exactly one row key column which is not part of the association key (in this case we don't need to persist the key name as it can be restored from the association key upon loading) or
• Entitys with keys/values for all row key columns which are not part of the association key

forEachTuple

public void forEachTuple(ModelConsumer consumer,
                         TupleTypeContext tupleTypeContext,
                         EntityKeyMetadata entityKeyMetadata)

Specified by:

public JsonEntityStorageStrategy getEntityStorageStrategy()

getTuples

public List<Tuple> getTuples(EntityKey[] keys,
                             TupleContext tupleContext)

Specified by:
