Ingestion from Pub/Sub’s BigQuery subscription into BigQuery costs $50/TiB based on read (subscribe throughput) from the subscription. This is a simpler and cheaper billing experience compared to the alternative path via Dataflow pipeline where you would be paying for the Pub/Sub read, Dataflow job, and BigQuery data ingestion.Pub/sub is: A way to decouple sending and receiving messages; A way to resiliently hold up to intense load; A mechanism to send one message to many different folks at once while keeping both parties ignorant of how the message moves around; Give pub/sub a try, it might just save you some headaches in the future!
