Query Bauplan-managed tables from BigQuery without moving or copying data. This walkthrough sets up an external Iceberg table in BigQuery that points directly at your Bauplan tables in S3.You deploy and evolve tables in Bauplan. Your analysts stay in BigQuery. The data stays in one place.What we cover:
