Frequently asked questions

What is the BigQuery connector?
The BigQuery connector lets you query your Google BigQuery data warehouse using plain English. Better Analyst translates your questions into optimized SQL, runs the query on your BigQuery project, and returns the results — all without you writing a single line of SQL.
What permissions does Better Analyst need?
Better Analyst requests read-only BigQuery authorization by default. We use OAuth 2.0 to authenticate securely through Google's official API. Read and write is requested only when you explicitly enable a Data Flow destination, and writes stay restricted to the approved dataset.
How do I connect BigQuery to Better Analyst?
Click "Connect BigQuery," sign in with your Google account, and select the project and dataset you want to analyze. The entire process takes less than a minute. No service account keys or manual configuration needed.
What data can I query with Better Analyst?
You can query any table or view in your BigQuery datasets that your Google account has access to. This includes standard tables, partitioned tables, and views. Ask questions about any data — Better Analyst will generate the appropriate SQL automatically.
Is my BigQuery data secure?
Yes. OAuth tokens and service-account credentials are encrypted, and results are encrypted in transit. Read only is the default. Read and write requires explicit authorization, a successful live probe, and Google IAM permission for the approved dataset.
Will Better Analyst affect my BigQuery costs?
Better Analyst runs standard BigQuery queries on your behalf, so standard BigQuery pricing applies. We optimize generated SQL to minimize data scanned. You can monitor query costs in your Google Cloud Console just like any other BigQuery usage.
