1. Exploring Mount Points in Databricks for Scalable Data Access


    In a Databricks environment, mount points are used to connect Databricks clusters to remote storage systems. This allows for scalable and efficient data access, as data can be read from and written to these storage systems directly. Utilizing mount points is a way to streamline data processing tasks by providing a way to access large data stores seamlessly.

    Below, I will provide you with a Pulumi program in Python that creates a Databricks workspace and defines a mount point to an S3 bucket. This is just an example; in a real-world scenario, you would replace any placeholder values with your actual AWS and Databricks account details. The mount would allow the Databricks clusters to access data stored in the specified S3 bucket.

    The program will leverage the databricks package available in Pulumi to manage Databricks resources and the aws package to manage AWS resources like the S3 bucket. Note that before running this Pulumi code, you would need to have the Pulumi CLI installed and configured with the appropriate cloud provider credentials.

    Let's walk through the program:

    1. Workspace Creation: We create a Databricks workspace. This is the environment where your data analytics will run.
    2. S3 Bucket Creation: An S3 bucket is created, which will serve as the data source or sink for the Databricks clusters.
    3. Mount Point Definition: A mount point is defined within the Databricks workspace pointing to the S3 bucket. This involves providing the necessary information, such as the AWS S3 bucket name and the role that has access to it.

    Please refer to the comments in the code for more details on each step.

    import pulumi import pulumi_aws as aws import pulumi_databricks as databricks # Create an AWS S3 bucket that we will mount to Databricks. s3_bucket = aws.s3.Bucket("my-databricks-bucket") # Create a Databricks workspace. databricks_workspace = databricks.Workspace("my-workspace") # Assume you have a role that Databricks can assume to access the S3 bucket. # This role's ARN is used to mount the bucket to databricks. # In this example, the ARN is hardcoded, replace it with your actual ARN. databricks_mount_role_arn = "arn:aws:iam::123456789012:role/databricks-s3-access-role" # Define the mount point. s3_mount = databricks.Mount("s3-mount", cluster_id=databricks_workspace.cluster_id, name="s3-mount-point", s3=databricks.MountS3Args( bucket_name=s3_bucket.bucket, instance_profile=databricks_mount_role_arn, ) ) # Export the URL of the bucket pulumi.export('bucket_url', s3_bucket.website_endpoint) # Export the mount point name pulumi.export('mount_point', s3_mount.name)

    To run this program, save it to a file (e.g., databricks_mount.py), set up your Pulumi stack, and run pulumi up from the command line. The Pulumi CLI will take care of provisioning all resources according to the program you wrote.

    Keep in mind to replace the placeholder databricks_mount_role_arn with a proper IAM role ARN from your AWS account that grants necessary permissions to Databricks to access the S3 bucket.
