我在这里看到示例https://cloud.google.com/dataflow/model/pubsub-io#reading-with-pubsubio for Java,但是当我看这里时https://github.com/apache/beam/blob/master /sdks/python/apache_beam/io/gcp/pubsub.py它说:
def reader(self):
raise NotImplementedError(
'PubSubSource is not supported in local execution.')
这意味着什么?Cloud Data Flow Python SDK PubSub Source/Sink 还没有准备好?
