You've developed an updated version of a Dataflow streaming pipeline that ingests data from Pub/Sub into BigQuery. The current production pipeline uses a 5-minute window for processing. How can you deploy the new version without risking data loss, inconsistencies, or exceeding a 10-minute increase in processing latency?
A
Cancel the old pipeline, then immediately start the new pipeline.
B
Update the existing pipeline with the new code directly.
C
Drain the old pipeline to process all existing data before starting the new one.
D
Take a snapshot of the old pipeline, stop it, and start the new pipeline from the snapshot.
