MicroProfile Config aggregates configurations from multiple sources, presenting a single merged view. It lets applications bundle default settings, which can be overridden or erased externally (e.g., via environment variables, system properties, or containers like Docker). Users can also implement custom configuration sources, such as reading values from a shared database in a cluster.
