1. Data Exploration and Visualization in Databricks Notebooks

    Python

    Data exploration and visualization in Databricks can be facilitated through the use of notebooks, which allow you to run live code, visualize results, and document the process with markdown. In the Pulumi context, you can manage and provision Databricks notebooks as infrastructure-as-code, which includes automating the deployment and configuration of these notebooks alongside your cloud infrastructure.

    To accomplish the goal of setting up data exploration and visualization with Databricks Notebooks using Pulumi, you will need to interact with the Databricks provider. Here's a breakdown of what that entails:

    1. Databricks Service Setup: First, you need an instance of the Databricks service. This might involve provisioning a Databricks workspace if it's not already available.

    2. Notebooks Management: You'll use Pulumi to create and manage Databricks notebooks. The databricks.Notebook resource allows you to upload a notebook file, specify the language (Python, Scala, R, or SQL), and handle notebook content.

    3. Visualization: While Pulumi does not directly handle visualization within the notebooks, once a notebook is set up, you can use Databricks' built-in functionality to visualize data—often using libraries like matplotlib for Python notebooks or ggplot2 for R.

    4. Automation: By wrapping the creation and updates of notebooks in Pulumi code, the data exploration environment can be version-controlled and made repeatable, shareable, and automated as part of your infrastructure.

    Below is a Pulumi Python program that provisions a new Databricks notebook, assumed that you have your Databricks instance running:

    import pulumi import pulumi_databricks as databricks # Create a new Databricks notebook in the given path with the specified language. notebook = databricks.Notebook("data-visualization-notebook", path="/Users/me/data_visualization", content_base64="base64-encoded-notebook-content", language="PYTHON", ) # Export the URL of the notebook. pulumi.export("notebook_url", notebook.url)

    In this program:

    • databricks.Notebook: A resource provided by Pulumi to manage Databricks notebooks. You must provide the path where the notebook will reside within the Databricks workspace and content encoded in base64.
    • path: Specifies the location in the Databricks workspace where the notebook is stored.
    • content_base64: The actual notebook content, encoded in base64. This content can be generated from a .dbc or .ipynb file.
    • language: The language of the notebook (e.g., 'PYTHON', 'SCALA', 'R', 'SQL').

    Before using this program, ensure you have the Databricks workspace available, and you've set up the appropriate access credentials to use the Databricks provider in Pulumi. Also, encode your notebook content to base64 before adding it to the script. You can find documentation about this process in the Databricks Notebooks documentation.

    Please remember that data visualization itself happens within the notebooks using specific code and libraries, and Pulumi is used to provision the notebooks and the infrastructure related to them. Once the notebook is in place, you can write Databricks code to handle your data exploration and visualization tasks.
