Are you looking to migrate your data from MySQL on Amazon RDS to Databricks? If so, you’ve come to the right place. Migrating data from MySQL on Amazon RDS to Databricks can be a complex process, especially when handling large datasets and different database structures. However, moving data from MySQL on Amazon RDS to Databricks can help you leverage analytical capabilities, obtain better insights, and enhance reporting efficiency.

While MySQL and Amazon RDS are fully managed cloud-based services, offering scalability, high availability, and automated backups for seamless data management. Databricks is a unified data analytics platform that combines data engineering, data science, and machine learning capabilities, empowering you to process and analyze large-scale data with ease and efficiency.

So, let’s look into the two popular methods for migrating data from MySQL on Amazon RDS to Databricks. 

Method 1: Move Data from MySQL on Amazon RDS Using CSV files

Using CSV files to load data from MySQL on Amazon RDS to Databricks involves the following steps:

Step 1: Export the Data on Amazon RDS MySQL into a CSV File

• Open the terminal or command prompt on your system. Enter the following command, replacing your_mysql_username with your actual MySQL username:

mysql -u your_mysql_username -p

Press Enter, and you will be indicated to provide your MySQL password. Type your password and press Enter. After entering the password, you will gain access to the MySQL Command-Line Interface, where you can start executing MySQL commands.

• To export your MySQL data from Amazon RDS into a CSV file, execute the following command:

mysql your_database --user=your_username --password=your_password --host=your-host.eu-west-2.rds.amazonaws.com --batch -e "SELECT * FROM table_name" | sed 's/\t/","/g;s/^/"/;s/$/"/;s/\n//g' > path/output.csv

Replace your_database, your_username, your_password, and table_name with your actual details. Ensure you provide the correct file path where you want to save the CSV file. Additionally, replace your-host.eu-west-2.rds.amazonaws.com with the specific endpoint of your Amazon RDS MySQL instance.

• Once you execute the command, your MySQL data on Amazon RDS will be saved in the output.csv file at the specified location on your system.

Step 2: Import the MySQL on Amazon RDS CSV File into Databricks 

• Log in to your Databricks account. Go to the Data tab and click on Add Data to begin the process of adding new data to your Databricks workspace. 
• Now, you can click the file browser button to open a file browser window. Use it to navigate through your local storage and select the files you want to import. Alternatively, you can directly drag and drop the files onto the Databricks workspace.
• After uploading the CSV file or files, Databricks will automatically process the data and display a preview. You can now create your own table to store this data.  

Using CSV files for data migration is indeed a time-consuming approach. However, the manual approach is particularly well-suited for one-time migrations. For occasional or infrequent data transfers, manual transfer can often be more straightforward compared to setting up complex automated processes.

While the manual method offers certain benefits, it also has several limitations. Some of these limitations include:

• Lack of Real-Time Integration: The process of manually transferring data from Amazon RDS MySQL to Databricks rds using CSV files lacks real-time integration. This means that any changes made in the MySQL database after the last CSV transfer will not be reflected in Databricks rds until they are manually uploaded.
• Inability to Handle Large Data Volumes: Using the CSV-based method to transfer data from Amazon RDS MySQL to Databricks is not ideal for handling large datasets. It is a time-consuming and resource-intensive process, making the migration less efficient and causing data transfer delays.
• Data Security Concerns: During the migration process storing the CSV files temporarily on the local system can indeed raise security concerns, particularly when handling sensitive or confidential data. It’s essential to implement proper security measures like data encryption and access control. 

Method 2: Automating the Data Replication Process Using a No-Code Tool

Step 1: Configure MySQL on Amazon RDS as Source

• Step 1.1: Click PIPELINES in the Asset Palette.
• Step 1.2: Next, click +CREATE in the Pipelines List View.
• Step 1.3: Then, on the Select Source Type page, select Amazon RDS MySQL.
• Step 1.4: In the Configure your Amazon RDS MySQL Source page.
• Step 1.5: Click TEST & CONTINUE.

Step 2: Configure Databricks as Destination

• Step 2.1: In the Asset Palette, select DESTINATIONS.
• Step 2.2: In the Destinations List View, click + CREATE.
• Step 2.3: Select Databricks from the Add Destination page.
• Step 2.4: Set the following parameters on the Configure your Databricks Destination page.
• Step 2.5: To test connectivity with the Databricks warehouse, click Test Connection.
• Step 2.6: When the test is complete, select SAVE DESTINATION.

Your migration from Amazon RDS to Databricks is now complete.
