MariaDB and MySQL are two widely popular relational databases that boast many of the largest enterprises as their clientele. Both MariaDB and MySQL are available in two versions – A community-driven version and an enterprise version. But the distribution of features and development processes in the community and enterprise versions of MySQL and MariaDB differ from each other. MariaDB and MySQL are closely related in the sense that MariaDB is a fork of MySQL.
Even though MariaDB claims itself as a drop-in replacement for MySQL, because of the terms of licensing and enterprising support contracts, many organizations migrate between these two according to their policy changes. This blog post will cover the details of how to move data from MariaDB to MySQL.

Introduction to MySQL
It provides a secure authentication layer with support for very granular field-level controls for reading and writing. MySQL supports table encryption as well as binary log encryption. Development processes in MySQL are more closed when compared to MariaDB and the issue trackers refer to many oracle internal sources that are closed for the public.

Introduction to MariaDB
MariaDB started as a fork of MySQL just before the acquisition of Sun microsystems by Oracle. The objective was to establish a purely open-source alternative to MySQL anticipating possible licensing constraints imposed by Oracle. Ever since Maria DB follows a different development path as compared to MySQL with the objective being to remain as similar as possible to MySQL from a user’s perspective. Many industry stalwarts like Microsoft and Alibaba back MariaDB and it is used by many of the top organizations for its day-to-day operations. MariaDB has a comprehensive SQL layer and provides a shell. It provides similar encryption capabilities as MySQL and is known to offer slightly higher performance and faster development cycles because of its open-source roots.

Methods to Connect MariaDB to MySQL
This method involves, building a Custom Code using the mysqldump command to move data from MariaDB to MySQL.
Hevo Data, a No-code Data Pipeline helps to load data from any data source such as Databases, SaaS applications, Cloud Storage, SDK,s, and Streaming Services and simplifies the ETL process. It supports MariaDB and MySQL, along with 100+ data sources (including 30+ free data sources). Hevo not only loads the data onto the desired Data Warehouse but also enriches the data and transforms it into an analysis-ready form without having to write a single line of code.Get Started with Hevo for Free
Methods to Connect MariaDB to MySQL
The following 2 methods can be used to transfer data from MariaDB to MySQL:
- Method 1: Using Custom Code to Connect MariaDB to MySQL
- Method 2: Using Hevo Data to Connect MariaDB to MySQL
Method 1: Using Custom Code to Connect MariaDB to MySQL
Since both the databases provide the same set of underlying tools, it is very easy to copy data from MariaDB to MySQL. The following steps detail how to accomplish this.
- Step 1: From the client machine, use the below command to create a complete dump of the database in MariaDB.
mysqldump -u username -p database_name > source_dump.sql
This command creates a source_dump.sql file.
- Step 2: Move the file to a machine that can access the target MySQL database. If the same machine has access to the target database, this step is not relevant.
- Step 3: Log in as root to the target MySQL database
mysql -u root -p password
- Step 4: In the MySQL shell, execute the below command to create a database.
CREATE DATABASE target_database;
Where target_database is the name of the database to which data is to be imported.
- Step 5: Exit the MySQL shell and go to the location where the source_dump.sql is stored.
- Step 6: Execute the below command to load the database from the dump file.
mysql -u username -p new_database < source_dump.sql
That concludes the process. The target database is now ready for use and this can be verified by logging in to the MySQL shell and executing a SHOW TABLES command. Even though this approach provides a simple way for a one-off copy operation between the two databases, this method has a number of limitations. Let’s have a look at the limitations of this approach.
MariaDB to MySQL: Limitations of Custom Code Approach
- In most cases, the original database will be online while the customer attempts to copy the data. mysqldump command is a costly execution and can lead to the primary database being unavailable or slow during the process.
- While the mysqldump command is being executed, new data could come in resulting in some leftover data. This data needs to be handled separately.
- This approach works fine if the copying operation is a one-off process. In some cases, organizations may want to maintain an exact running replica of MariaDB in MySQL and then migrate. This will need a complex script that can use the binary logs to create a replica.
- Even though MariaDB claims itself as a drop-in replacement, the development has been diverging now and there are many incompatibilities between versions as described here. This may lead to problems while migrating using the above approach.

The article introduced MariaDB and MySQL and explained 2 methods using which you can connect MariaDB to MySQL. The manual custom coding method provides a simple approach for a one-off migration between MariaDB and MySQL. But, this is not suitable for continuous or periodic copying operation. This method also suffers from some other limitations mentioned above. An alternative could be using a data integration platform like Hevo which can handle such migrations in an elegant way without having to write a single line of code.Visit our Website to Explore Hevo
