Package com.hazelcast.config

Class DataPersistenceConfig

java.lang.Object
com.hazelcast.config.DataPersistenceConfig
All Implemented Interfaces:
DataSerializable, IdentifiedDataSerializable
public class DataPersistenceConfig extends Object implements IdentifiedDataSerializable
Configures the Persistence per Hazelcast data structure.

Note: If either, but not both, data-persistence (DataPersistenceConfig) or hot-restart (HotRestartConfig) is enabled, Hazelcast will use the configuration of the enabled element. If both are enabled, Hazelcast will use the data-persistence (DataPersistenceConfig) configuration. hot-restart element (and thus HotRestartConfig) will be removed in a future release.
