+#### BigQuery
+
+Use a BigQuery DSN like `bigquery://<project>/<dataset>` (or `bigquery://<project>/<location>/<dataset>`). The driver
+uses `GOOGLE_APPLICATION_CREDENTIALS` to locate the service account JSON file. In Kubernetes, follow the existing
+pattern used for Snowflake/Trino: set `SQLEXPORTER_TARGET_DSN` from a Secret and mount the service account JSON from a
+Secret, then set `GOOGLE_APPLICATION_CREDENTIALS` to the mounted file path.
+
+To target a specific reservation per query, add a `reservation` query parameter to the DSN, for example:
+`bigquery://<project>/<dataset>?reservation=projects/<project>/locations/<location>/reservations/<reservation>`.
+The driver prefixes each query with `SET @@reservation='...'`, which uses BigQuery multi-statement scripting. See
+[BigQuery reservation assignments](https://docs.cloud.google.com/bigquery/docs/reservations-assignments#reservation).
