Package com.arpnetworking.utility

Class Database

java.lang.Object
com.arpnetworking.utility.Database
All Implemented Interfaces:
Launchable
public class Database extends Object implements Launchable
Database instance abstraction across database technologies: HikariCP, Flyway and EBean. NOTE: The current configuration process of mapping to classes and then instantiating components from "safe" configuration is a complete falacy. Only by attempting to apply (e.g. restart) the system with the new configuration can you determine if it is truly safe. Once rewritten that way configuration classes can be eliminated in many cases and the raw Configuration object mapped directly to the consumer of that configuration. For example, in this class we could read a subkey for Hikari thus decoupling our configuration from Hikari's. The same can be done for Flyway by automatically converting a subkey into a Properties instance and giving it to Flyway.
