# getAsyncMultiMap

`open fun <K : Any, V : Any> getAsyncMultiMap(name: String, resultHandler: Handler<AsyncResult<AsyncMultiMap<K, V>>>): Unit`

Every eventbus handler has an ID. SubsMap (subscriber map) is a MultiMap which maps handler-IDs with server-IDs and thus allows the eventbus to determine where to send messages.

### Parameters

`name` - A unique name by which the the MultiMap can be identified within the cluster. See the cluster config file (e.g. cluster.xml in case of HazelcastClusterManager) for additional MultiMap config parameters.

`resultHandler` - handler receiving the multimap
