What you gain

✓No per-TB query pricing that spikes with analyst activity
✓Full control over data warehouse without Google Cloud dependency
✓No slot-based pricing for reserved compute capacity
✓Self-hosted analytics with no egress fees on query results

What you give up

△No BigQuery ML for training models directly in SQL
△No managed columnar storage with automatic optimization
△No BigQuery BI Engine for sub-second dashboard queries
△No native Looker and Google Sheets integration

Switching Cost

BigQuery's lock-in is the SQL dialect and ecosystem integration. Your data exports to Parquet or CSV, but the BigQuery-specific SQL functions, ML models trained in BigQuery ML, and scheduled queries need rewriting. Teams with simple reporting queries can migrate in a few days. Teams with complex data pipelines, UDFs, and BigQuery ML models should budget 2-4 weeks. The hidden cost is the Looker/Sheets integration: if your business users run reports directly from BigQuery through connected sheets or Looker dashboards, every one of those connections needs rebuilding.

Building Blocks

BigQuery is a platform. It bundles multiple capabilities into one subscription. These tools each cover one piece. Teams often assemble 2–3 of them instead of paying for the full suite.
