Solved: Use a different Quota Project For BigQuery - Page 2

nachi_napo · 03-27-2024 11:38 PM

Hi community,
I was trying to use a different quota project (other than my resource project where my BQ data resides). I set the quota project in Java program by using BigQueryClientOptions and assigned Service Usage Consumer IAM role in the quota project to my test service account. The application runs fine after that. Here are my questions

1. I couldn't find out a way to verify if the quota project was accounted for all my application workloads. Could you please guide me on how to do that?
2. General question about quota project - will it be used only when the quota of resource project exceeds or it'll be used as first priority irrespective of whether or not quota is exceeding the resource project?

Artifacts - code used to create client

BigQuery bigquery = BigQueryOptions.newBuilder()
        .setCredentials(creds) // holds service account details.
        .setProjectId(projectId)
        .setQuotaProjectId(quotaProjectId)
        .build()
        .getService();

Using a quota project in Google Cloud BigQuery is a strategic approach to manage billing and quota usage across multiple projects. This setup allows you to separate the project where your resources are located (the resource project) from the project against which your quota and billing are counted (the quota project).

1. Verifying Quota Project Usage

To verify if the quota project is being accounted for your application workloads, you can use the following methods:

Google Cloud Console:
- Navigate to the "Billing" or "IAM & Admin" > "Quotas" sections in your quota project.
- Monitor usage metrics for BigQuery to confirm your application is using the quota project.
Billing Reports: Access detailed billing reports in the quota project to see if BigQuery charges are attributed correctly.
Audit Logs: Examine audit logs in the quota project for BigQuery-related entries to track requests and ensure they are tied to the quota project.

2. General Information About Quota Project Usage

Immediate Usage: Operations performed using the BigQuery client configured with a quota project are immediately attributed to the quota project, regardless of the resource project's quota status.
Priority: The quota project takes precedence for quota and billing purposes.

Code Snippet Review

Your code snippet is correct:

 

BigQuery bigquery = BigQueryOptions.newBuilder() 
    .setCredentials(creds) // holds service account details.  
    .setProjectId(projectId) // Resource project 
    .setQuotaProjectId(quotaProjectId) // Quota project 
    .build() 
    .getService(); 

This configuration ensures that while your BigQuery resources reside in the projectId, the quotaProjectId handles quota and billing for operations performed through this client instance.
