Relational Storage for AI Data Preprocessing Workflows on GCP

Question

Pulumi · Accepted Answer

Relational storage is essential for AI data preprocessing workflows, as it enables the structured organization and querying of data, which can be critical for preparing datasets for machine learning models. On Google Cloud Platform (GCP), Cloud SQL is a fully-managed relational database service that supports MySQL, PostgreSQL, and SQL Server. It allows you to set up, maintain, manage, and administer your relational databases on GCP.

To use Cloud SQL for AI data preprocessing workflows on GCP, you would need to set up a Cloud SQL instance, create databases and tables as necessary, and connect this relational storage to your data preprocessing services or tools.

In Pulumi, you can create a Cloud SQL instance using the `DatabaseInstance` class from the `pulumi_gcp` package. You will also require a database within the instance and a user for accessing the database. Below is a Python Pulumi program that demonstrates how to create a PostgreSQL Cloud SQL instance, a database, and a user on GCP.

The resources used in this example are:

- `gcp.sql.DatabaseInstance`: This resource creates a new Cloud SQL instance. You can choose the database engine and version, among other configuration options.
- `gcp.sql.Database`: This resource is used to create a new database within a Cloud SQL instance.
- `gcp.sql.User`: This resource creates a new user with permissions to access the databases within the Cloud SQL instance.

Here's the program to set up relational storage for AI data preprocessing workflows:

```python
import pulumi
import pulumi_gcp as gcp

# Create a Cloud SQL instance for PostgreSQL
sql_instance = gcp.sql.DatabaseInstance("sql-instance",
    database_version="POSTGRES_12",
    region="us-central1",
    settings=gcp.sql.DatabaseInstanceSettingsArgs(
        # Define the machine type and disk size
        tier="db-f1-micro",
        data_disk_size_gb=10,
        # Enable automatic backups and binary logging
        backup_configuration=gcp.sql.DatabaseInstanceSettingsBackupConfigurationArgs(
            enabled=True,
            binary_log_enabled=True,
        ),
    )
)

# Create a PostgreSQL database within the Cloud SQL instance
sql_database = gcp.sql.Database("sql-database",
    name="preprocessing_db",
    instance=sql_instance.name,
    # Set the charset and collation for the database
    charset="UTF8",
    collation="en_US.UTF8",
)

# Create a user for the PostgreSQL database
sql_user = gcp.sql.User("sql-user",
    name="preprocessor",
    instance=sql_instance.name,
    password="strong-password-here",  # Use a strong, secure password in practice
)

# Export the connection name of the Cloud SQL instance, which is used to connect applications to the database
pulumi.export("sql_instance_connection_name", sql_instance.connection_name)
```

Before running this program, ensure that you've configured your GCP credentials correctly with Pulumi and have set the necessary permissions for creating Cloud SQL instances and related resources.

Once you've created your Cloud SQL instance and configured it for your data preprocessing workflows, you would connect your AI and machine learning tools to this relational storage to manage your datasets more efficiently. It's also important to manage access and security properly, ensuring that only authorized applications and users can access your data.
