Class ClusterShardingSettings

  • All Implemented Interfaces:
    NoSerializationVerificationNeeded

    public final class ClusterShardingSettings
    extends java.lang.Object
    implements NoSerializationVerificationNeeded
    param: role specifies that this entity type requires cluster nodes with a specific role. If the role is not specified all nodes in the cluster are used. param: rememberEntities true if active entity actors shall be automatically restarted upon Shard restart. i.e. if the Shard is started on a different ShardRegion due to rebalance or crash. param: journalPluginId Absolute path to the journal plugin configuration entity that is to be used for the internal persistence of ClusterSharding. If not defined the default journal plugin is used. Note that this is not related to persistence used by the entity actors. param: snapshotPluginId Absolute path to the snapshot plugin configuration entity that is to be used for the internal persistence of ClusterSharding. If not defined the default snapshot plugin is used. Note that this is not related to persistence used by the entity actors. param: passivationStrategySettings settings for automatic passivation strategy, see descriptions in reference.conf param: tuningParameters additional tuning parameters, see descriptions in reference.conf param: shardRegionQueryTimeout the timeout for querying a shard region, see descriptions in reference.conf
