True ETL Tools
If you need more than just to copy data from Brevo to AlloyDB, you may use Skyvia's powerful ETL functionality for Brevo and AlloyDB integration. Skyvia's Import tool will correctly extract Brevo data, transform it, and load to AlloyDB when AlloyDB tables have different structure than Brevo 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 Brevo and AlloyDB 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.
