public SelectBrokerRouteFromLocalCache ( string topic, byte key = null ) : KafkaNet.BrokerRoute | ||
topic | string | The topic to retreive a broker route for. |
key | byte | The key used by the IPartitionSelector to collate to a consistent partition. Null value means key will be ignored in selection process. |
