Explore the rationale behind moving database drivers for MySQL, MariaDB, PostgreSQL, and SQLite to separate modules in Drupal 9.4. Learn about the challenges faced with the previous setup, including issues with composer compatibility, database-specific overrides, and test variations. Discover how this change enables new possibilities, such as asynchronous query execution using PHP 8.1's Fibers functionality and storing content entity data in document format for improved performance. Gain insights into the potential benefits of using MongoDB as a database solution for Drupal, and understand how this approach could reduce reliance on caching, particularly for authenticated users. Participate in a group discussion to share ideas and shape the future direction of Drupal's database architecture.
