  22. def shardRegion(typeName: String): ActorRef

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

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

  23. def start(typeName: String, entryProps: Props, messageExtractor: MessageExtractor): ActorRef

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

    Java API: Register a named entry type by defining the akka.actor.Props of the entry actor and functions to extract entry 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.

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

    typeName

    the name of the entry type

    entryProps

    the Props of the entry actors that will be created by the ShardRegion, if not defined (null) the ShardRegion on this node will run in proxy only mode, i.e. it will delegate messages to other ShardRegion actors on other nodes, but not host any entry actors itself

    messageExtractor

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

    returns

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

  24. def start(typeName: String, entryProps: Props, messageExtractor: MessageExtractor, allocationStrategy: ShardAllocationStrategy): ActorRef

    messageExtractor

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

    allocationStrategy

    possibility to use a custom shard allocation and rebalancing logic

    returns

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

  25. def start(typeName: String, entryProps: Option[Props], idExtractor: IdExtractor, shardResolver: ShardResolver): ActorRef

    the Props of the entry actors that will be created by the ShardRegion, if not defined (None) the ShardRegion on this node will run in proxy only mode, i.e. it will delegate messages to other ShardRegion actors on other nodes, but not host any entry actors itself

    idExtractor

    partial function to extract the entry id and the message to send to the entry 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

    shardResolver

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

    returns

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