问题描述
我正在尝试使用Google提供的模板PubSub to BigQuery设置数据流作业.我看到一个用于指定Cloud Pub/Sub输入订阅的选项，但是在GCP控制台UI中看不到用于指定Pub/Sub输入订阅的任何选项.
I am trying to setup a Dataflow job using the google provided template PubSub to BigQuery. I see an option to specify the Cloud Pub/Sub input topic but I don't see any option to specify Pub/Sub input subscription in GCP console UI.
如果我提供主题，则job将自动创建一个订阅以读取提供的主题中的消息.问题是，在Dataflow作业启动后，该作业将仅看到发布到该主题的消息.之前在同一主题上发表的任何内容都将被忽略.
If I provide the topic, job would automatically create a subscription to read the messages from the provided topic. Problem with this is, the job will see only messages published to the topic after the Dataflow job has started. Anything published before to the same topic would be ignored.
我的工作没有任何复杂的转变.因此，谷歌提供的模板将为我开箱即用.但是缺乏指定我自己的订阅的能力令我感到困扰.为此，我不想设置自定义作业管道.有人知道是否有解决方法吗?
I don't have any complex transformations to do in my job. So the google provided template would work for me out of the box. But the lack of ability to specify my own subscription is bothering me. I don't want to setup a custom job pipeline just for this reason. Anybody know if there is a workaround for this?

That's not currently supported. However its a great use case and is on the Google Cloud Team's radar.
