In modern Angular and microservices-based applications, managing data consistency and reliability is a persistent challenge and often relies on backend API stability.
One of the biggest challenges in blue-green deployments is managing data consistency when both environments share the same database. While this approach simplifies the process, it requires careful planning around schema changes and backward compatibility to ensure smooth transitions without data conflicts.
With virtual generated columns, we avoid using additional disk storage. Instead, the database calculates their value on demand, for example, during a query. However, PostgreSQL currently lacks support for the virtual generated columns.
