Class HotRestartPersistenceConfig

java.lang.Object
com.hazelcast.config.HotRestartPersistenceConfig
@Deprecated(since="5.0") public class HotRestartPersistenceConfig extends Object
Deprecated.
use PersistenceConfig
Configures the Hot Restart stores.

Hot restart stores are used to hold copy of in-memory data in disk to be able to restart very fast without needing to load data from a central storage.

HotRestartConfig configures whether hot restart is enabled, where disk data will be stored, should data be persisted sync or async etc.

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

      public HotRestartPersistenceConfig setAutoRemoveStaleData(boolean autoRemoveStaleData)
      Deprecated.
      Sets whether automatic removal of stale Hot Restart data is enabled.

      When a member terminates or crashes when cluster state is ClusterState.ACTIVE, remaining members redistributes data among themselves and data persisted on terminated member's storage becomes stale. That terminated member cannot rejoin the cluster without removing Hot Restart data. When auto-removal of stale Hot Restart data is enabled, while restarting that member, Hot Restart data is automatically removed, and it joins the cluster as a completely new member. Otherwise, Hot Restart data should be removed manually.

      Parameters:
      autoRemoveStaleData - true to enable auto-removal of stale data, false otherwise
      Returns:
      HotRestartPersistenceConfig
