Should You Use Hibernate's hbm2ddl.auto=update in Production?

Is Hibernate's hbm2ddl.auto=update a Good Option for Production Environments?

Setting hbm2ddl.auto=update in Hibernate may seem convenient for managing database schema changes during development. However, using this setting in a production environment is strongly discouraged for several reasons.

Firstly, it is inherently unsafe. Despite Hibernate's efforts, automatic schema updates cannot be entirely reliable in a production environment. Complexities in data structures, constraints, and dependencies can lead to unexpected errors or data loss. It is crucial to manually review and apply database patches tested thoroughly before deployment.

Secondly, hbm2ddl.auto=update can potentially sub-optimize database performance. Skilled DBAs understand database nuances and can craft patches that are more efficient and tailored to the specific environment. By relying on automatic updates, you bypass their expertise, potentially leading to performance issues.

In conclusion, while hbm2ddl.auto=update may be useful in development, it is highly inadvisable to use it in production environments. Maintaining database schema integrity and performance requires manual patches and careful collaboration with DBAs.
