  22. def shardRegion(typeName: String): ActorRef

    Retrieve the actor reference of the ShardRegion actor responsible for the named entity type.

    Retrieve the actor reference of the ShardRegion actor responsible for the named entity type. The entity type must be registered with the #start method before it can be used here. Messages to the entity is always sent via the ShardRegion.

  23. def start(typeName: String, entityProps: Props, settings: ClusterShardingSettings, messageExtractor: MessageExtractor): ActorRef

    Java/Scala API: Register a named entity type by defining the akka.actor.Props of the entity actor and functions to extract entity and shard identifier from messages.

    Java/Scala API: Register a named entity type by defining the akka.actor.Props of the entity actor and functions to extract entity and shard identifier from messages. The ShardRegion actor for this type can later be retrieved with the #shardRegion method.

    The default shard allocation strategy ShardCoordinator.LeastShardAllocationStrategy is used. akka.actor.PoisonPill is used as handOffStopMessage.

    Some settings can be configured as described in the akka.cluster.sharding section of the reference.conf.

    typeName

    the name of the entity type

    entityProps

    the Props of the entity actors that will be created by the ShardRegion

    settings

    configuration settings, see ClusterShardingSettings

    messageExtractor

    functions to extract the entity id, shard id, and the message to send to the entity from the incoming message

    returns

    the actor ref of the ShardRegion that is to be responsible for the shard

    allocationStrategy

    possibility to use a custom shard allocation and rebalancing logic

    handOffStopMessage

    the message that will be sent to entities when they are to be stopped for a rebalance or graceful shutdown of a ShardRegion, e.g. PoisonPill.

    returns

    the actor ref of the ShardRegion that is to be responsible for the shard

  25. def start(typeName: String, entityProps: Props, settings: ClusterShardingSettings, extractEntityId: ExtractEntityId, extractShardId: ExtractShardId): ActorRef

    extractEntityId

    partial function to extract the entity id and the message to send to the entity from the incoming message, if the partial function does not match the message will be unhandled, i.e. posted as Unhandled messages on the event stream

    extractShardId

    function to determine the shard id for an incoming message, only messages that passed the extractEntityId will be used

    returns

    the actor ref of the ShardRegion that is to be responsible for the shard
