BigQuery定时查询因加载位置europe-west8报错中断，如何修改相关设置？

Let’s walk through the key spots to track down that rogue europe-west8 reference that’s stopping your scheduled queries—even though you’ve set everything to US regions:

1. Dig into your scheduled query’s SQL and hidden settings #

Even if you selected us in the UI, your query might be quietly pointing to europe-west8 resources:

• Scan the full SQL of your failing scheduled query for hardcoded references to europe-west8 datasets, tables, or storage buckets (like in EXPORT DATA clauses).
• Check the "Advanced options" of the scheduled query—look for any fields related to temporary storage or output locations that might have inherited the wrong region.

2. Verify BigQuery Data Transfer Service’s default location #

The Data Transfer Service (which powers scheduled queries) has its own global default setting that might be misconfigured:

• Go to the BigQuery Data Transfer Service page in the Google Cloud Console.
• Click the gear icon (settings) at the top of the page.
• Check if the default location is set to europe-west8—if so, switch it to a US region like us-central1 or us-east1.

3. Double-check all linked storage buckets (including hidden ones) #

You mentioned setting 4 buckets to US regions, but scheduled queries might use other buckets you haven’t considered:

• Check the scheduled query’s target settings to see if it’s using a specific bucket for temp data.
• Go to your BigQuery project settings (left sidebar → Project settings) and verify the location of your project’s default temporary storage bucket.

4. Confirm your Google Cloud project’s default region #

Your project’s overall default region can leak into Data Transfer Service behavior:

• Head to IAM & Admin > Settings in the Google Cloud Console.
• Look for "Default region" and "Default zone"—make sure both are set to US-based values (not europe-west8 or any EU region).

5. Check the query’s run logs for clues #

The failure logs often have more granular details about where the europe-west8 call is coming from:

• Open the failing scheduled query’s details page.
• Go to Run history, click on the most recent failed run, then select View logs.
• Search for europe-west8 in the logs—this should highlight exactly which step is triggering the error.

If none of these fix it, try creating a simple test scheduled query (e.g., INSERT INTO your-us-table VALUES ('test')) to see if the error persists. That will help narrow down whether it’s a problem with your specific query or a broader project setting.
