Built by some of the original developers of MySQL, MariaDB is an RDBMS based on SQL, offering technical efficiency and versatility. The database is used for many purposes, including data warehousing and retrieving and managing data. Leveraging its relational nature and open-source community, MariaDB has been shown to perform better than MySQL. Walmart, Alibaba, and Accenture are just a few names on the list of the major organizations that use MariaDB in their tech stacks. 

Here are some of the key features of MariaDB: 

  • MySQL Compatibility: MariaDB was originally designed to be a drop-in replacement for MySQL. This means that most MySQL code can work seamlessly with MariaDB. Leveraging this compatibility, you can use MySQL’s syntax, commands, and APIs in its ecosystem without making significant changes.
  • Multiple Storage Engines: In MariaDB, a storage engine functions as a distinct plugin tailored to specific use cases. Each storage engine is meticulously optimized for different types of data workloads, ranging from transactional to analytical. MariaDB supports multiple storage engines for various data and workloads, including InnoDB, Aria, TokuDB, and others. 
  • Security: MariaDB comes equipped with robust security features as a default, ensuring the protection of your database. This includes connections through TLS/SSL encryption between the client and database server, preventing unauthorized access. Additionally, frequent security feature updates on MariaDB make it a reliable choice if you are dealing with sensitive data. 

MySQL Overview

Originally developed by a Swedish company MySQL AB, which was then acquired by Oracle in 2010, MySQL stands is one of the most popular open source RDMSs. It allows you to store and organize data in structured collections within tables characterized by columns and rows. With MySQL, you can define, query, control, and manipulate data using Structured Query Language (SQL).

As a part of the widely used tech stack LAMP (Linux, Apache, MySQL, and PHP), MySQL is used to build many popular services, websites, and applications. Major organizations such as Uber, Airbnb, Pinterest, and Shopify rely on MySQL for their database management needs, showcasing its versatility and robustness in handling large-scale operations. 

Below are the key features of MySQL: 

  • ACID Compliance: MySQL follows ACID (Atomicity, Consistency, Isolation, Durability) compliance to ensure data integrity and consistency. Atomicity ensures that every operation contained with a transaction is handled as an individual unit. Consistency makes sure that data is valid before and after a transaction. Isolation prevents multiple concurrent transactions from interfering with each other. Durability ensures that transaction modifications are saved permanently, even in system failure. 
  • IAM Policy: MySQL in Oracle cloud infrastructure integrates with Identity and Access Management (IAM) for the authorization and authentication of all interfaces such as console, SDK, CLI, or a RestAPI. IAM allows you to centrally handle access to your data instead of managing each instance on your DB. 
  • Free to Use: MySQL is open-source, so you can download, install, and use MySQL without any licensing cost. This feature allows you to leverage all the functionalities of a robust database management system without many barriers. However, some commercial versions of this platform, like MySQL Cluster Carrier Grade Edition and MySQL Enterprise Edition, are also available.

Method 2: Manually Connecting MariaDB to MySQL Using Custom Code

In this method, you’ll learn how to migrate MariaDB to MySQL manually using custom code. Follow this step-by-step guide to replicate data between the two databases:

Step 1: Create a Dump of MariaDB 

Begin by generating a dump of the MariaDB database you want to migrate.

  • Open the terminal and type the following command: 
mysqldump -u yourusername -p yourdatabasename > maria_dump.sql
  • Replace yourusername with your MariaDB database username, and yourdatabasename with the database name you want to migrate. The file maria_dump.sql is where your data will be exported.

Step 2: Log in to MySQL as a Root User

  • Using the terminal, navigate to the SQL directory "C:\Program Files\MySQL\MySQL Server X.X\bin" (replace X.X with your actual version number) and enter the following command:
mysql -u root -p password
  • Provide your MySQL password when prompted.

Step 3: Create a MySQL Database

  • To create a new database in MySQL, enter the following code:
CREATE DATABASE yoursqldatabasename;
  • Replace yoursqldatabasename with your preferred MySQL database name. Check that the database was created and exit the MySQL session. 

Step 4: Restore the Data 

  • Now that you have your MariaDB data file and the MySQL database set up, it’s time to restore the data into the new database. To import the MariaDB data into MySQL, enter the following command into your terminal: 
mysql -u yourusername -p yoursqldatabasename < maria_dump.sql

Step 5: Verify and Test

Once the migration is completed, ensure that the MariaDB data is successfully migrated into the MySQL table. Run SQL queries or test your application to make sure everything functions as it should.

Limitations of Using Custom Code

The following are some challenges you might encounter when manually connecting MariaDB to MySQL using custom code: 

  • Time and Resource Requirements: Developing, testing, and maintaining custom scripts can be time-consuming and require more development expenses than ETL tools. 
  • Maintenance Challenges: Custom scripts need regular updates to accommodate changes in database schemas or system upgrades. This ongoing requirement demands constant effort. 
  • Expertise Requirements: A deep understanding of MariaDB and MySQL databases is required to write custom code for migration. Mistakes or inefficiencies in custom code can result in performance problems, data loss, and more. 
  • Latency in Real-Time Updates: Executing custom scripts may result in delays and, in some cases, cause a lack of real-time synchronization between databases. This is a notable drawback if you want real-time updates across systems and applications.
