MySQL as Destination

UnifyApps enables seamless integration with MySQL databases as a destination for your data pipelines. This article covers essential configuration elements and best practices for loading data into MySQL destinations.

Overview

MySQL is widely used for web applications, online transaction processing, and e-commerce platforms. UnifyApps provides native connectivity to load data into these MySQL environments efficiently and securely, making it ideal for operational databases, web application backends, and real-time data stores.

Prerequisites

Before configuring MySQL as your destination, ensure you have:

MySQL Server Instance: Access to an active MySQL Server instance (version 5.6 or later recommended)
Connection Information: Server hostname/IP address, port number (default 3306), and database name
Authentication Credentials: MySQL username and password with appropriate privileges

Database Privileges: The user needs CREATE, INSERT, UPDATE, and DELETE privileges on the target database:

GRANT 
    CREATE, INSERT, UPDATE, DELETE 
ON 
    `<database_name>`.* 
TO 
    'unify_writer'@'%';
FLUSH PRIVILEGES;

Network Connectivity: Proper firewall rules allowing access on MySQL port

Connection Configuration

Parameter	Description	Example
`Connection Name`*	Descriptive identifier for your connection	"Production MySQL Data Store"
`Project`	Optional project categorization	"Web Application Backend"
`Host Address`*	MySQL server hostname or IP address	"mysql-app.example.com"
`Port Number`*	Database listener port	3306 (default)
`User`*	Database username with write permissions	"unify_writer"
`Password`*	Authentication credentials	"********"
`Database Name`*	Name of your target MySQL database	"application_db"
`Server Time Zone`*	Database server's timezone	"UTC"
`Connection`*	Method of connecting to the database	Direct or Via SSH

To set up a MySQL destination, navigate to the Connection Manger, click New Connection, and select MySQL as destination. Fill in the parameters above based on your MySQL environment details.

Authentication

Connection Name: Choose a meaningful name for your destination connection, such as "E-commerce MySQL Database"
Project: Optional project categorization to organize your connections
Database Host: The MySQL database server's IP address or DNS hostname
Database Port: The port on which your MySQL server accepts connections (default: 3306)
Database User: The authenticated user with permissions to create and modify tables in your target database
Database Password: The password for the database user
Database Name: Name of the target MySQL database where data will be loaded
Server Time Zone: The timezone setting of your MySQL server for proper timestamp handling

Schema Mapping

MySQL as Destination in UnifyApps supports Manual Mapping only. This provides precise control over data transformation and loading:

Define custom column names and MySQL-specific data types
Apply data transformations during the mapping process
Handle MySQL data structures with precision
Ensure data quality through explicit mapping definitions
Optimize for MySQL's storage engines and indexing capabilities

During pipeline configuration, you'll manually specify the mapping between source fields and MySQL destination columns, enabling optimal data transformation for your application requirements.

Supported Data Types

UnifyApps handles these MySQL data types for destination loading, ensuring proper conversion from your source systems:

Category	Supported Types
`Integer`	TINYINT, SMALLINT, MEDIUMINT, INT, BIGINT
`Decimal`	NUMERIC, FLOAT, DOUBLE, DECIMAL
`Date/Time`	DATE, DATETIME, TIMESTAMP, TIME
`String`	CHAR, VARCHAR, TEXT
`Binary`	BINARY, VARBINARY, BLOB
`Boolean`	BOOLEAN (alias for TINYINT(1))
`Bit-field`	BIT

All common MySQL data types are supported, enabling comprehensive data loading into various MySQL applications.

Implement proper indexing strategy for query performance
Monitor and optimize MySQL configuration parameters

Monitoring and Maintenance

Performance Monitoring

Track data loading times and throughput rates
Monitor MySQL server resource utilization during pipeline execution
Use MySQL performance schema for detailed query analysis
Set up alerts for long-running or failed operations

Database Maintenance

Schedule regular maintenance windows for optimization tasks
Monitor database size and plan for storage growth
Implement appropriate backup and recovery procedures
Maintain MySQL connection pool settings for optimal performance

MySQL's reliability and performance make it an excellent destination for data pipelines supporting web applications and operational systems. By following these configuration guidelines and best practices, you can ensure reliable, efficient data loading that meets your application requirements for performance, scalability, and data integrity.
