Azure MySQL to Redshift: Optimizing Data Warehousing Capabilities

Imagine you are managing a rapidly growing e-commerce platform. That platform generates a large amount of data related to transactions, customer interactions, product details, feedback, and more. Azure Database for MySQL can efficiently handle your transactional data. But as your business grows, so does the associated data, making it difficult to process and analyze these big datasets. 

AWS Redshift is a data warehouse that can help you tackle these challenges. Redshift’s columnar storage and massive parallel processing architecture (MPP) assist you in handling large-scale workloads smoothly and quickly. By migrating your data from Azure MySQL to Redshift, you can improve your operational performance and gain deeper customer insights. 

This article will explore the methods for smoothly integrating data from Azure MySQL to Redshift. Let’s get started.

Why Integrate Data from Azure MySQL to Redshift?

Data migration from Azure MySQL to Redshift offers several advantages that can significantly benefit organizations.

How to Integrate Azure MySQL to Redshift

Method 1: Integrating Data from Azure MySQL to Redshift Using Hevo 

Hevo is a real-time ELT platform streamlining your data integration process with no-code, cost-effective, and flexible data pipelines. The data pipeline can be set up quickly and with minimal effort. Hevo also provides 150+ data sources from which you can export data to your desired destination. 

Benefits of Using Hevo 

• Data Transformation: Hevo offers two types of data transformation: Python-based and drag-and-drop.This feature helps you clean and enrich your source data before ingesting it into your desired destination, making it analysis-ready. 
• Incremental Loading: Hevo’s incremental loading allows you to load only recently modified and updated source data into your destination instead of loading all the data again.
• Automated Schema Mapping: This feature automatically reads and replicates the source schema to the targeted destination. 

Now, let’s look at the steps to connect and load data from Azure MySQL to Redshift by building a data pipeline in Hevo.

Step 1: Configure Azure MySQL as Your Source 

Prerequisites

• Check if your Azure MySQL database is running. 
• The MySQL version that you are using should be 5.7 or higher. 
• Enable Binary Log Replication if the data pipeline is in BinLog mode.
• Check if your Hevo’s IP addresses are Whitelisted.
• Create a Database user and Grant select and replication privileges to them.
• Check if your source instance’s database hostname and port number are available.
• To create a data pipeline in Hevo, you must be assigned the role of Team Collaborator, Team Administrator, or Pipeline Administrator.

Step 2: Configure Amazon Redshift as Your Destination 

Prerequisites

• Set up and check if your Amazon Redshift instance is running. 
• Check if your Amazon Database instance for Redshift is available.
• Check if your database hostname and port number for the Redshift instance are available.
• Create a database user and grant SELECT privileges.
• You should be assigned any administrative role except for the Billing Administrator to create the destination in Hevo. 

Hence, your data will be replicated from Azure MySQL to Redshift.

Method 2: Export Data from Azure MySQL to Redshift File Using CSV File 

Step 1: Export Azure MySQL Data to a CSV File

You can export Azure MySQL data to a CSV file using MySQL Workbench. 

Prerequisites

• Connect your MySQL workbench to your MySQL database, which is hosted on Azure. 
• Provide details on setting the connection, such as the username and password.

You can access the Data Export Wizard from the Navigator pane on your MySQL Workbench to export data to a CSV File. 

Follow the steps below: 

• Go to the Navigator Pane and select the Data Export Wizard. 
• Select all the schemas you want to export to the CSV file in the Data Export window. 
• Choose a database object to export and configure the other related options. 
• Select Refresh to load all the objects that are present. 
• Click on Start Export to export and save data to a CSV file. 

Step 2: Import Data from a CSV File to AWS S3 Bucket

Prerequisites

• Create a user and grant permissions to create an S3 bucket and access data from it.
• Grant COPY command permissions to the user to read the file object in the S3 bucket.
• Download and extract the CSV files from your local system.
• Create an Amazon S3 bucket in the same AWS region as your cluster.
• Create a folder where the S3 bucket will be stored. 

Follow the steps below to upload the data from the CSV file to the S3 bucket. 

• Go to the Upload wizard and select the Add Files option. 
• Select the CSV file that you want to upload from your local system. 
• Select the Upload option to load the files in your S3 bucket.

Step 3: Export Data from a S3 Bucket to Amazon Redshift Instance

Prerequisites

• Check if you have the necessary IAM role permissions to upload data into your Redshift Instance. 
• Create and Launch the Amazon Redshift cluster along with database tables. 
• Check if you have an SQL client, such as the Redshift console query editor. 

You can create tables in your database and copy data into them using the COPY command on the Amazon Redshift query editor.

Load Data to Your Redshift Database Instance from an S3 Bucket

• Load the data from the S3 bucket to the Redshift table and execute the command below. 

COPY table_name [ column_list ] FROM data_source CREDENTIALS access_credentials [options] 

       Here: 

• table_name refers to the targeted table in your Redshift DB instance. 
• column_list refers to the column in the targeted tables where you want to map the data. 
• data_source refers to the data path of the data file. 
• access_credentials refers to the AWS access credentials that are required for authorization.

Limitations for Method: Export Data from Azure MySQL to Redshift File Using CSV File 

• If you want to import data in a CSV file using the data wizard on the MySQL workbench, you need to manually configure mapping options and column selection. This can be difficult for individuals who are unfamiliar with data wizards’ functionalities. 
• You need Insert privileges and other permissions to use the COPY command with the Amazon Redshift cluster. Configuring and maintaining access rights in an environment where users have varied levels of data access can be challenging.
• You cannot directly import the data from CSV files to the Amazon database instance for Redshift, making the process more lengthy and complicated.
