True ETL Tools
If you need more than just to copy data from MariaDB to Azure MySQL, you may use Skyvia's powerful ETL functionality for MariaDB and Azure MySQL integration. Skyvia's Import tool will correctly extract MariaDB data, transform it, and load to Azure MySQL when Azure MySQL tables have different structure than MariaDB objects. Moreover, Skyvia Import allows loading data in any direction, supporting Reverse ETL scenario.
For more complex cases, you can use Data Flow and Control Flow tools. They are designer-based solutions for creating complex data pipelines, involving not only MariaDB and Azure MySQL connectors, but any number of connectors in one integration. With these tools you can automate data workflows, involving custom logic, complex multistage transformations, combine data from different sources, load them into multiple destinations at once and many more.
