But here we are going to connect with multiple DB instances at a time parallelly. These are the below steps:

Step 1: Create a mule project with default configuration.

Step 2: Add Database module from Anypoint exchange.

Step 3: We are passing Db connection details as payload. And we can pass these details with variables also.?

To connect with MySQL DB we have to provide Host, Port, Username, Password parameters.

Step 4: Create a DB configuration to connect with MySQL DB instances. We have to get connection details from payload as shown below in the screenshot.

Step 5: Select connection as MYSQL connection, And select Required libraries as mysql maven dependency, Click on finish. You should see this maven dependency in your project's? pom.xml file.
