Businesses of all sizes use GCP MySQL, a managed relational database service, for its reliability and robust capabilities in handling structured data. However, as data volumes grow and analytics become more complex, GCP MySQL can face challenges in scalability and performance.

These limitations significantly impact businesses, as slower query performance and the inability to handle growing datasets can hinder a business’s ability to analyze data. By integrating GCP MySQL to Databricks, you can unlock significant benefits.

The Databricks distributed architecture enhances scalability in data storage and processing and helps eliminate bottlenecks associated with traditional databases. Additionally, its integration with Apache Spark greatly improves query performance, allowing you to gain insights faster for greater agility and real-time decisions. 

Why Integrate GCP MySQL to Databricks?

Integrating GCP MySQL to Databricks offers several compelling benefits, including:

  • Scalability on Demand: Databricks decouple storage and computing, allowing each to scale independently based on workload requirements. Integrating GCP MySQL to Databricks allows you to handle any volume of data without significant infrastructure changes, enabling applications to scale seamlessly as data volumes increase.
  • Improved Query Performance: Databricks is built on top of Apache Spark, benefiting from Spark’s massively scalable framework. Additionally, the Photon engine of Databricks can significantly speed up queries, providing you with quicker insights. 
  • Unified Analytics Platform: Unlike GCP MySQL, which is primarily a database management system, Databricks provides a unified platform for data engineering, data science, and analytics. This integration allows easier collaboration among data professionals and reduces the time required to go from raw data to actionable insights.
  • Seamless Data Integration: Databricks provides a cloud-agnostic architecture, allowing you to work with multiple cloud providers without vendor lock-in. This enables greater flexibility and the ability to easily integrate data from various sources.

Google Cloud Platform (GCP) for MySQL Overview

Google Cloud Platform (GCP) offers a robust environment for managing MySQL databases through its fully managed database service, Cloud SQL for MySQL. The service simplifies the setup, management, and maintenance of MySQL databases, allowing you to focus more on application development rather than database operations. 

GCP for MySQL supports high availability, automatic backups, and seamless scalability, optimizing database performance without manual intervention. It easily integrates with other GCP services such as App Engine, Compute Engine, Google Kubernetes Engine, etc. This facilitates easier and more secure data management and accessibility, making GCP a preferred choice for enterprises looking to leverage cloud capabilities for their MySQL database needs.

Databricks Overview

Databricks is a cloud-based platform designed to streamline data engineering, data science, and analytics. The platform offers a unified environment for processing large datasets, building machine learning models, and extracting actionable insights. Databricks leverages Apache Spark, an open-source big data processing engine, providing a robust foundation for distributed computation.

The Databricks Lakehouse architecture is a standout feature that differentiates it from other platforms. The architecture combines the benefits of data lakes, renowned for their flexible storage, with those of data warehouses, known for their data governance capabilities. This empowers teams to seamlessly analyze all their data, regardless of format, and discover valuable insights.

Methods to Integrate GCP MySQL to Databricks

There are multiple ways to import GCP MySQL to Databricks, which can be classified based on ease of use and required technical skills. In this section, we will look into two methods and provide a step-by-step guide on how to integrate GCP MySQL to Databricks.

Method 1: Using the CSV Export/Import Method to Convert GCP MySQL to Databricks Table

This method uses Google Cloud Console to transfer GCP MySQL data to Databricks as CSV files. Here are the steps:

Step 1: Exporting the Data from GCP MySQL as CSV Files

Before you can export data from Cloud SQL for MySQL, ensure that you have the required roles and permissions.

Prerequisites

1) The user must have one of the following roles to export data from Cloud SQL: 

2) The service account for the Cloud SQL instance requires either of the following roles:  

  • storage.objectAdmin Identity and Access Management (IAM) role 
  • Or a custom role with the below permissions:
    • storage.objects.create
    • storage.objects.list 
    • storage.objects.delete

Note: Changes to IAM permissions and roles might require a few minutes to take effect.

Here are the steps to export your GCP MySQL data as CSV.

  • In the GCP console, navigate to the Cloud SQL Instances Page.
  • Find the instance you want to export from and click on it to view its Overview Page.
  • Next, click the Export button.
  • Enable the Offload export option to allow other operations during the export.
  • Click Show advanced options to reveal additional export settings.
  • From the drop-down menu in the Database section, select the name of the database from which you want to export data.
  • Enter the SQL query that specifies the table from which you want to export data. 

For example, to export all rows from the entries table in the guestbook database, you would enter:

SELECT * FROM guestbook.entries;

  • Click Export to start the CSV export process.

Step 2: Using Databricks DBFS File Explorer to Import the CSV Dataset

DBFS File Explorer is a tool for uploading and downloading files to and from the Databricks filesystem (DBFS). It provides a highly interactive user interface for managing files and supports both AWS and Azure instances of Databricks. Here are the steps to import CSV data using DBFS file explorer:  

  1. Enable DBFS File Browser

First, we must enable the Databricks DBFS file browser in the workspace settings in Databricks. This allows you to upload files from the UI into DBFS. 

To do this, log in to your Databricks workspace and click Admin Settings

  1. Creating Tables From Uploaded Files

Now that the file upload is complete, you must create a table to interact with the uploaded data. Databricks DBFS provides two ways to accomplish this.

  • Option 1: Create Table with UI

Once you select this option, a cluster selection menu appears. Choose the cluster you want to use and preview the table.

Now, you can easily query the table using SQL or other supported languages.  

  • Option 2: Create Table in Notebook

Selecting this option opens a notebook interface for creating and analyzing a table. You can use SQL or programming languages like Python, R, Scala, etc for the analysis.

After loading the CSV data into a table, you can use Databricks SQL or Notebook to query, transform, and analyze it. You can also join, aggregate, filter, and visualize the data as needed for your specific use case.

Limitations of Using CSV Export/Import Method

  • Technical Expertise: The CSV export/import method requires an advanced understanding of the Google Cloud ecosystem and Databricks. Additionally, proficiency in one or more programming languages, such as Python, SQL, or Scala, is essential. As a result, it isn’t well-suited for beginners.
  • Lack of Real-Time Data Integration: Manual migrations are typically batch processes; data moves in parts at specific intervals. This introduces delays and inconsistencies between the source and target systems, hindering decision-making processes that rely on up-to-date information.
  • Security Risks: Manually moving data often involves downloading it to local systems, transferring it across networks, and sometimes using intermediate storage solutions. This increases the overall risk of data breaches, unauthorized access, or unintentional exposure of sensitive information.
