Step 3: Create a Database User and Grant Privileges

To create a new database user, you must connect to your Aurora MySQL database as a root user using the SQL client tool, such as MySQL workbench. Replace the <username> placeholder from the given code with your own credential:

CREATE USER <username>@'%' IDENTIFIED BY '<password>';

You can perform the steps given below in order to grant privileges to the user:

  • Using an SQL Client tool, you must connect to your Aurora MySQL database as a root user.
  • Grant the SELECT and REPLICATION privileges to the user by following the command given below by replacing the <username> placeholder:
  • Allow Hevo to access your database using this command:
GRANT SELECT ON <database-name>.* TO <username>;
  • If ingestion mode is set to Binlog to grant access to the database user to read BinLog settings:
GRANT EXECUTE ON PROCEDURE mysql.rds_show_configuration TO '<username>'@'<hostname>';

Step 4: Settings to Establish Amazon Aurora MySQL Connection:

Learn more about configuring Amazon Aurora as a source in Hevo’s documentation. 

On the Configure your Amazon Aurora MySQL Source page, specify the necessary fields:

  • Pipeline Name: A unique name that is less than 255 characters.
  • Database Host 
  • Database Port: The port on which your Aurora MySQL server listens for a connection.
  • Database User
  • Database Password
  • Select an Ingestion Mode: It is set to BinLog by default.

For the Connection Settings, enable the Connect through SSH option. This helps you connect to Hevo using an SSH tunnel. To use an SSL encrypted connection, enable Use SSL and specify the CA File, Client Certificate, and Client Key.

Additionally, you have the option to enable Load All Databases, which is applicable for BinLog mode. Choosing this option allows Hevo to load the data from all the databases onto the specified host.

You also have the option to enable Load Historical Data, Merge Tables, and Include New Tables in the Pipeline according to your requirements.

Finally, click on TEST CONNECTION and select TEST & CONTINUE.

Specify Object and Query Mode Settings

After specifying the source connection settings, select an ingestion mode:

  • If your pipeline is in Table or BinLog mode:
    • On the Select Objects page, choose the object you want to replicate and click CONTINUE. Remember that each object represents a table in your database.
Aurora MySQL: Select Objects
Select Objects
  • For each selected object, specify the query mode you want to use on the Configure Objects page.
Aurora MySQL: Configure Objects

Provide Query Settings

By following the given steps, you can configure Amazon Aurora MySQL as a source in your data pipeline. To learn more about the steps, you can refer to the Amazon Aurora MySQL Hevo Documentation page.

2. Setting up MySQL as a Destination

To set MySQL as a destination of your data pipeline through Hevo Data, you must ensure you meet all the prerequisite conditions.

  • The MySQL server must be running (not in a local host environment). To check this, copy and paste the given command into your MySQL instance:
service mysql status

This command will show you a result as Active: active (running) if the condition is satisfied.

  • Run the following command to check the MySQL version; it must be 5.5 or higher:
mysql -V
Step 1: Whitelist Hevo IP Address for Your Region

Here, you will require root access or sudo privileges to perform some commands. Follow the steps to whitelist the Hevo IP address for your region:

  • Navigate to the MySQL configuration directory and open the MySQL server configuration file in edit mode.
sudo nano /etc/mysql/mysql.conf.d/mysqld.cnf

The filename mentioned in the above example will depend on the location of your server configuration file.

  • Update the bind-address variable by scrolling to the [mysqld] section in any one of the following ways:
    • To allow any IPv4 address to connect to your MySQL destination, you need to specify:
bind-address =

To allow any specific Hevo IP address for your region:

bind-address =
  • To make changes, restart the MySQL server after saving the file.

For any version of MySQL above 8.0, you must add the bind-address variable if it is not present in the [mysqld] section. You also need to delete the skip-networking variable, as it will allow the MySQL server to listen to remote connections.

Step 2: Create and Grant Privileges to a Database User

To create a database user, you need to be logged in to your MySQL database instance using the SQL client tool as a root user. Use the command by replacing the placeholder values:

CREATE USER '<user_name>'@'%' IDENTIFIED BY '<strong password>';

Grant necessary privileges to the user by following the steps below:

  • Log in to your MySQL server as a root user.
  • Enter the following commands by replacing the placeholder values to grant the required privileges to the database user:
GRANT ALTER, CREATE, CREATE TEMPORARY TABLES, DELETE, DROP, INSERT, SELECT, UPDATE ON <database_name>.* to <user_name>@<IP address> IDENTIFIED BY <user_password>;
Step 3. Configure MySQL Connection Settings
  • In the Navigation Bar, click DESTINATIONS.
  • Select + CREATE in the Destinations List View.
  • Select MySQL on the Add Destination page.
  • Specify the mandatory details in the Configure your MySQL Destination page. This includes Destination Name, Database Host, Database Port, Database User, Database Password, and Database Name.
Aurora MySQL Integration: Configure your MySQL Destination
Configure your MySQL Destination

Additionally, you can enable Connect through SSH. Enable the Use SSL option by specifying CA File, Client Certificate, and Client Key, and Sanitize Table/Column Names to remove non-alphanumeric characters and spaces.

Finally, you must click on TEST CONNECTION and select SAVE & CONTINUE.

You must disable the foreign keys defined in the target tables since they do not allow data to be transferred until the reference table contains the associated key. This method can only replicate 4090 columns in a MySQL table. To learn more, refer to Limits on the Number of Columns.

To learn more about the steps, you can refer to Hevo Data MySQL Documentation.

Method 2: Using Amazon S3 for Aurora MySQL Data Migration

In this method, you will be using Amazon S3 for Amazon Aurora MySQL data integration.

1. Transfer Data from Aurora MySQL to S3

Follow the steps in this section to move your data from the Aurora MySQL instance to Amazon S3. For better clarification, you can also read the official AWS Documentation.

Step 1: Grant Aurora MySQL Access to Amazon S3
  • After creating a new AWS identity and Access Management policy (IAM), allow your Aurora MySQL DB cluster to access Amazon S3. You can refer to Creating an IAM policy.
  • You need to create an IAM role and associate the IAM policy you created in the previous step with the new IAM role. To complete this step, you can go through the Create an IAM role documentation.
  • For Aurora MySQL version 2, configure either the aws_default_s3_role or  aurora_select_into_s3_role DB cluster parameter to the Amazon Resource Name of the new IAM role. For the Aurora MySQL version 3, use aws_default_s3_role. To know more about DB cluster parameters, read DB cluster and DB instance parameters.
  • Associate the role that you created in the previous step with the DB cluster to permit the database user in an Aurora MySQL DB cluster to access Amazon S3. You can read more about associating IAM roles with DB clusters.
  • Allow outbound connections to Amazon S3 from Aurora MySQL DB cluster by following Enable network connection from Aurora to AWS services guide.
Step 2: Grant Privileges to Save Data in Aurora MySQL

You can use either of the given code snippets to grant necessary privileges to save data in Aurora MySQL.

For Aurora MySQL version 3, use the following statement by removing the placeholders:

GRANT AWS_SELECT_S3_ACCESS TO 'user'@'domain-or-ip-address'

For Aurora MySQL version 2, you can use the statement given below:

GRANT SELECT INTO S3 ON *.* TO 'user'@'domain-or-ip-address'

These privileges are specific to Aurora MySQL.

Step 3: Specifying a Path to an Amazon S3 Bucket

You need to specify the path of the Amazon S3 Bucket to store the data files. You can find this path from the LOAD DATA FROM S3 PREFIX statement. You can use this syntax to specify the path by replacing the variable values with your own required location.

Step 4: Create a Manifest to List the Data Files

You must use the MANIFEST ON option with the SELECT INTO OUTFILE S3 statement to generate JSON manifest files listing created files inside S3. The LOAD DATA FROM S3 statement loads back into the data files into the Aurora MySQL DB cluster using the manifest file.

The order of the data is organized to resemble the SELECT INTO OUTFILE S3 specifications.

Step 5: SELECT INTO OUTFILE S3 Statement

You can query data from a DB cluster using the SELECT INTO OUTFILE S3 statement and save it directly into the Amazon S3 bucket. Follow the syntax below by replacing the placeholder values:

    select_expr [, select_expr ...]
    [FROM table_references
        [PARTITION partition_list]
    [WHERE where_condition]
    [GROUP BY {col_name | expr | position}
        [ASC | DESC], ... [WITH ROLLUP]]
    [HAVING where_condition]
    [ORDER BY {col_name | expr | position}
         [ASC | DESC], ...]
    [LIMIT {[offset,] row_count | row_count OFFSET offset}]
INTO OUTFILE S3 's3_uri'
[CHARACTER SET charset_name]
    [ENCRYPTION {ON | OFF | SSE_S3 | SSE_KMS ['cmk_id']}]

        [TERMINATED BY 'string']
        [[OPTIONALLY] ENCLOSED BY 'char']
        [ESCAPED BY 'char']
        [STARTING BY 'string']
        [TERMINATED BY 'string']

Use the FORMAT argument to save this in a CSV file. The SELECT INTO OUTFILE S3 statement returns a MySQL error number as a response to success or failure. If you cannot access the error number, you can use MANIFEST ON to find its whereabouts.

2. Download Your Data File from Amazon S3

Since you have transferred your data into an Amazon S3 bucket, you must follow the steps given to download your data:

  • First, you need to open the Amazon S3 console by signing in to your AWS Management Console.
  • From the Buckets list, you need to choose the name of the bucket where you stored the data.
  • You need to select the checkbox next to the object and choose Download. Alternatively, you can also download the object to a specific folder using the Actions menu and choosing Download as.

3. Loading Data to MySQL

It’s time to get your answers about “How to insert Aurora data in MySQL table.” You can load data into your MySQL workbench by following the steps mentioned below:

  • You need to create a table that matches the columns and the datatypes of your CSV data file.
  • Right-click on the table to select the Table Data Import Wizard option, and browse through your local storage to select the data file.
  • Configure the import settings by selecting the file encoding and matching the source and destination columns. Then click on the Next button.
  • You can check for the imported data using this simple command. Be sure to remove the placeholder with the original table name:
SELECT * FROM ‘data_table_name’’

By following the steps in this method, you can copy data from Aurora to MySQL.

Limitations of Amazon S3 for Aurora MySQL Data Migration

There are certain limitations that you must know of before using Amazon S3 for Aurora MySQL data migration:

  • Time-Consuming: This method consumes your valuable time since you are required to manually perform all the tasks. It expects your attention while moving Aurora data to a MySQL location.
  • Errors During Migration: The S3 method can lead to data duplication or errors if you are not extra careful during the Amazon Aurora MySQL data replication process. 
  • Technical Expertise: You must possess sufficient technical knowledge to move data and create tables to store and process the incoming data.

Use Cases of Aurora MySQL Integration

  • Cost Optimization: Moving Amazon Aurora data to MySQL reduces the cost of managing data. Even though Aurora provides certain benefits in terms of performance and scalability, using MySQL reduces the overall costs.
  • Data Backup: Aurora MySQL integration provides a better data backup. You will have more control over the data when it is present in MySQL.
  • Experimentation Benefits: Connecting Aurora to MySQL enables you to conduct experiments on the data in your database. You can run A/B testing on your data to determine which factors suit your business better.
