✓ verified Jun 9, 2026 ✓ install

Official Python client for Google BigQuery. Current version: 3.40.1 (Mar 2026). v3.0 made google-cloud-bigquery-storage and pyarrow required dependencies. Authentication uses Application Default Credentials (ADC) — no explicit API key. query() returns a QueryJob — must call .result() to wait for completion. to_dataframe() dtype behavior changed in v3 (nullable pandas dtypes). Python 3.9+ required as of v3.x.
