Topic 1 Question 31
You have Google Cloud Dataflow streaming pipeline running with a Google Cloud Pub/Sub subscription as the source. You need to make an update to the code that will make the new Cloud Dataflow pipeline incompatible with the current version. You do not want to lose any data when making this update. What should you do?
Update the current pipeline and use the drain flag.
Update the current pipeline and provide the transform mapping JSON object.
Create a new pipeline that has the same Cloud Pub/Sub subscription and cancel the old pipeline.

Correct Option : A Explanation:-This option is correct as the key requirement is not to lose the data, the Dataflow pipeline can be stopped using the Drain option. Drain options would cause Dataflow to stop any new processing, but would also allow the existing processing to complete
