1. Dataflow as ETL for AI Model Training Data

    Python

    Dataflow is a fully managed service offered by Google Cloud Platform for stream and batch data processing. It's commonly used for Extract, Transform, Load (ETL) operations, which are integral to pre-processing data for AI model training.

    In the context of setting up such an ETL pipeline using Pulumi, we will consider a scenario where we want to ingest data from a source, transform it, and then make it available for training an AI model. Here's a high-level overview of the process:

    1. Extract: Data is read from a data source such as Google Cloud Storage (GCS).
    2. Transform: The data is processed and transformed into a suitable format for AI model training, which may include operations like filtering, aggregation, join, or format conversion.
    3. Load: The processed data is loaded into a storage system, such as a BigQuery dataset, where it can be accessed by the AI model training service.

    Now, let's write a Pulumi program in Python that sets up a Google Dataflow job for this purpose. We will use the gcp.dataflow.Job resource to define our Dataflow job, specifying the transformation steps and input/output locations.

    Here's the Pulumi program that accomplishes the ETL task using Google Dataflow:

    import pulumi import pulumi_gcp as gcp # Assuming that we already have the template and other resources set up in GCS # Here, `gs://my-bucket/path/to/template` is the path to the Dataflow template # and `gs://my-bucket/path/to/temp_location` is the GCS path for temporary files used during job execution dataflow_job = gcp.dataflow.Job( "etl-job", template_gcs_path="gs://my-bucket/path/to/template", temp_gcs_location="gs://my-bucket/path/to/temp_location", parameters={ "inputFile": "gs://my-data-bucket/input/data.csv", # Source data to be processed "outputTable": "my_project:my_dataset.processed_data" # Destination for the processed data in BigQuery }, max_workers=5, zone="us-central1-a", # Choose the appropriate zone machine_type="n1-standard-1", # Specify the machine type based on processing requirements network="default", # Use the appropriate VPC network region="us-central1", # Set the region for the Dataflow job ) # Export the job's id which can be used to track its status pulumi.export("dataflow_job_id", dataflow_job.id)

    This Pulumi program defines a Dataflow job using an existing template, specifying both the source data and the output destination for the transformed data. It also sets the job's compute resources and networking configurations.

    Explanation:

    • We import the required Pulumi modules for GCP.
    • We define a Dataflow job resource named etl-job.
    • The template_gcs_path property refers to the path of the Dataflow template stored in a GCS bucket that defines the job's graph of transformations.
    • The temp_gcs_location is the path where temporary files will be stored during the job's execution.
    • The parameters dictionary details the specific inputs for this Dataflow job, including the source data file path and the BigQuery output table.
    • The max_workers, zone, machine_type, network, and region properties configure the compute resources and network settings for the job.
    • Finally, we export the Dataflow job's ID as an output of the Pulumi program.

    The Pulumi program should run "out of the box" if you have the Pulumi CLI and GCP provider configured with the necessary credentials and permissions. Remember to replace the paths, project IDs, datasets, and regions with the ones applicable to your GCP environment.

    By running this program, you'll create a Dataflow job that can be monitored and managed through the GCP console, Pulumi Console, or CLI. After completion, the job will have transformed and loaded the data suitable for AI model training.
