Hi, I have a use-case, where I get updates through GCP Pub/Sub stream. I get the file names from Pubsub and I want to read those files through Flink. I'm able to get fileNames through PubsubSource via flink-pubsub-connector. But I'm stuck at how to read these files dynamically now. env.readTextFiles will only accept pre-defined paths, so how to do this in streaming fashion ?
