Class ClusterShardingSettings

java.lang.Object

akka.cluster.sharding.typed.ClusterShardingSettings

public final class ClusterShardingSettings
extends java.lang.Object

param: numberOfShards number of shards used by the default HashCodeMessageExtractor 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. If the given role does not match the role of the current node the ShardRegion will be started in proxy mode. param: dataCenter The data center of the cluster nodes where the cluster sharding is running. If the dataCenter is not specified then the same data center as current node. If the given dataCenter does not match the data center of the current node the ShardRegion will be started in proxy mode. 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: passivationStrategySettings settings for automatic passivation strategy, see descriptions in reference.conf 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: tuningParameters additional tuning parameters, see descriptions in reference.conf
