@Beta public interface DiscoveryStrategyFactory
DiscoveryStrategyshould have its own factory building it. In rare cases (like multiple version support or similar) one factory might return different provider implementations based on certain criteria. It is also up to the DiscoveryStrategyFactory to cache instances and return them in some kind of a Singleton-like fashion. The defined set of configuration properties describes the existing properties inside of the Hazelcast configuration. It will be used for automatic conversion, type-checking and validation before handing them to the
DiscoveryStrategy. This removes a lot of boilerplate from the provider vendor and provides some convenience as well as guarantee to execute the expected configuration checks. The later is especially important because there is no schema support for properties necessary or provided by the provider plugins. Any kind of violation while verification of any type conversion error as well as missing non-optional properties will throw an exception and prevent the node from starting up.
