Spring xd 使用Kafka作为消息总线的直接绑定部署

我正在尝试对以下流使用直接绑定

stream create --definition "time | log" --name ticktock
stream deploy ticktock --properties module.*.count=0

在admin和container节点上部署失败，出现此异常：

java.lang.IllegalArgumentException: Module count cannot be zero

我有一个SpringXD（1.2.0）集群，其中有一个管理节点和两个容器节点，使用Kafka作为消息总线

我做错什么了吗？或者直接绑定和Kafka消息总线有问题吗？

根据，XD

Kafka消息总线目前不支持直接绑定

注意：Kafka消息总线不支持模块部署的count=0，因此不支持模块的直接绑定。此功能将在将来的版本中提供。同时，如果卡夫卡部署需要模块之间的直接通信，则应使用复合模块
