Why each option
This question tests knowledge of designing a hybrid data pipeline on GCP that handles both real-time vehicle telemetry streaming and large-scale daily batch uploads efficiently.
Streaming directly to BigQuery and running nightly aggregate jobs addresses batch reporting but does not provide a scalable, decoupled real-time pipeline for the subset of critical telemetry that must be processed immediately.
Pub/Sub decouples real-time data ingestion from processing; Dataflow provides a unified stream and batch processing engine that can aggregate telemetry and write results to Cloud Storage or BigQuery, meeting the real-time fleet management requirement with managed, auto-scaling infrastructure.
Parallel composite uploads break large daily sensor files into smaller chunks uploaded simultaneously to Cloud Storage, dramatically reducing upload time for the 200-500 MB per vehicle files generated by 2 million vehicles, then further processing can occur downstream.
BigQuery Data Transfer Service is designed for scheduled transfers from specific SaaS sources and data warehouses, not for ingesting arbitrary compressed sensor binary data uploaded from field vehicles.
