In 2026, Adobe designated MariaDB the default and recommended database for Adobe Commerce and Magento Open Source, and announced that MySQL 8.4 will be the last MySQL version the platform ever supports. For an ecosystem of tens of thousands of stores built on MySQL, this is the most significant infrastructure change in years - and it raises practical questions for every merchant, agency, and hosting provider.

This session looks at the transition from the database side. What exactly did Adobe announce, and what timelines does it set? What does a MySQL-to-MariaDB migration involve in practice - effort, risk, compatibility, and how to fold it into an upgrade cycle instead of treating it as a separate project? And what does the move unlock: lifecycle and performance advantages, and capabilities the MySQL line does not offer, including native vector search that brings semantic product discovery into the database a store already runs.
