How Python Data Engineers Use Google Cloud Storage

GCS is the central data lake for Python pipelines on Google Cloud. Engineers use the `google-cloud-storage` client to read raw event files or CSV exports, and write Parquet pipeline outputs back to GCS bucket prefixes. BigQuery loads data directly from GCS, making it the standard staging area for batch ingestion into the warehouse.
