Create Cloud SQL read replicas

Creating read replicas in Cloud SQL allows you to offload read-heavy workloads from your primary instance, improving performance and scalability. Here's how you would theoretically create Cloud SQL read replicas:

1. Accessing Cloud SQL: Open the Google Cloud Console and navigate to the Cloud SQL page.

2. Select the Primary Instance: Choose the primary Cloud SQL instance from which you want to create a read replica.

3. Navigate to Replicas: Within the instance details page, locate the "Replicas" tab or section.

4. Click on "Create Replica": Click on the "Create Replica" button to initiate the creation process.

5. Configure Replica Settings: Provide the necessary configuration details for the read replica, including:

   • Replica name: Specify a unique name for the read replica.
   • Region: Choose the region where you want to deploy the replica.
   • Machine type: Select the machine type and storage capacity for the replica.
   • Automatic backups: Choose whether to enable automatic backups for the replica.
