The video discusses the shared database antipattern in microservices, highlighting its drawbacks such as loss of scalability, resilience, and independence. It suggests using a database per service pattern to avoid these issues. The video also covers the benefits of shared databases, like easier transaction management and data consistency, but warns of serious drawbacks. The polygode persistence principle is introduced, allowing different data storage technologies for different services. Finally, guidance is provided on choosing the right database for microservices, emphasizing the importance of understanding usage requirements.

What is the database per service pattern and why is it recommended?

In what scenarios might it be more appropriate to use a monolithic approach instead of microservices?
