Step 1: Configure Amazon RDS MySQL as Source

Step 2: Configure Azure Synapse as Destination

That’s it! You’ve successfully set up your Amazon RDS MySQL to Azure Synapse pipeline in two steps using the Hevo platform.

Method 2: Load Data from MySQL on Amazon RDS to Azure Synapse

This approach divides the integration and replication process into three distinct steps. To begin, we’ll export data from AWS RDS for MySQL into CSV files. Next, the downloaded files will be uploaded to Azure Blob Storage. Finally, the data will be replicated from the storage container to Synapse.

To build MySQL on Amazon RDS to Azure Synapse ETL pipeline, simply follow these steps:

Step 1: Move Data from AWS RDS for MySQL into CSV Files

• Establish a connection with your AWS RDS MySQL instance
• Log in to your AWS Management Console.
• Navigate to the Amazon RDS service and select your MySQL database instance.
• On the Connectivity & Security tab, get the connection details, including the endpoint, port, username, and password.
• Access MySQL Database
• Use a MySQL client tool or command-line utility like MySQL Workbench or MySQL CLI to connect to your RDS MySQL instance using the database details.
• Export Data to CSV
• Run a SQL query to export the data into a CSV file using the SELECT INTO OUTFILE statement. Here’s an example of a SQL query to export data from a table named “Amazon_rds” into a CSV file named information.csv:

SELECT * 
INTO OUTFILE '/information.csv' 
FIELDS TERMINATED BY ',' 
ENCLOSED BY ‘ “ ‘ 
LINES TERMINATED BY '\n' 
FROM Amazon_rds;

• After executing this, check the specified path to ensure that the CSV file has been created and contains the desired data.

Step 2: Load CSV to Azure Blob Storage

To load CSV files to Azure Synapse Analytics, you would need to use an intermediary storage service like Azure Blob Storage. It is a cloud-based object storage service provided by Microsoft Azure. Azure Blob Storage seamlessly integrates with other Azure services and tools, making it simple to build data-driven workflows within the Azure ecosystem.

To begin, copy the CSV files from the local machine to Azure Blob Storage using Azure CLI (AzCopy) or Azure portal. Then use Azure Blob Storage connector to transfer the data from Azure Blob Storage to Azure Synapse Analytics. 

Here we’ll proceed with the AzCopy command to replicate CSV files data to Azure Synapse.

• Install and configure Azure CLI.
• Open a terminal and run the following command to sign in to your Azure account:

az login

• Create a new Azure Blob Storage Container using the following command:

az storage container create --Azure Blob Storage container --account name --account key

Replace ‘Azure Blob Storage container’ with desired container name, ‘account name’, and ‘account key’ with your Azure Blob Storage account name and key.

• Copy CSV files to Azure Blob Storage Container using AzCopy:

azcopy copy '/path/to/local/directory/*.csv' 
'https://storage-account.blob.core.windows.net/your-container-name/' 
--your-storage-account-name --your-storage-account-key

Replace ‘/path/to/local/directory/*.csv’ with the local directory path containing the CSV files. Mention the URL of the Azure Blob Storage container where you want to copy the CSV files.

The Azcopy command will upload all CSV files with .csv extension from the specified local directory to the Azure Blob Storage container.

Step 3: Upload to Azure Synapse

• Create a new data flow in Azure Synapse Studio.
• Navigate to the Develop hub and click on the + New button to create a new Data Flow.
• Add Source Transformation

• In the data flow canvas, drag and drop the Source transformation.
• Use the Azure Blob Storage connector as the data source.
• Configure the source transformation to point to your Azure Blob Storage container containing CSV files. Provide the necessary connection details, such as Azure Blob Storage account name, container name, and access key.
• Add Sink Transformation
• Drag and drop the Sink transformation. 
• Choose Azure Synapse Analytics as the data sink and provide the required connection details, including server name, database name, and authentication method.
• You can auto-detect the column mapping function or manually map them using the Mapping tab in the Sink transformation.
• Preview and Execute
• Click on the Data Preview tab to preview the data coming from the source transformation.
• After validating the data click on Publish. Execute the data flow to move data from Azure Blob Storage to Azure Synapse.

You’ve successfully established MySQL on Amazon RDS Azure Synapse integration.

While using a manual method and CSV files is time-consuming and effort-intensive, it is better suited for one-time backups. The manual approach with CSV files offers a feasible solution for one-time transfers from RDS MySQL to Synapse with small data volumes. It is efficient and manageable for one-time backups, as you don’t need to invest in specialized software.

Limitations of Manual Migration from MySQL on Amazon RDS to Azure Synapse

When loading data from MySQL on Amazon RDS to Azure Synapse using CSV files, there are several limitations to keep in mind:

• Latency: The data from AWS RDS MySQL needs to be exported in CSV format and saved in Azure Blob Storage before loading it into Azure Synapse. This introduces additional steps and can be time-consuming for larger datasets. It also requires regular manual interventions for data updates, data integrity, and schema mapping, which could impact data availability.
• File Size Limitations: In Azure Blob Storage, a block refers to a smaller piece or chunk of data that creates a larger file called a Block Blob. A Block Blob can include up to 50,000 blocks (5TB), and each block can be up to 100 MB in size. If your CSV files are greater than 100 MB, you might need to split them into blocks to accommodate the block size limitation.

As this process involves manual intervention at each stage, it often includes various challenges and limitations as well. To overcome these limitations, sign up for Hevo’s 14-day free trial and experience the ease of seamless data migration.
