Interface CacheTopologyValidatorProvider

All Superinterfaces:

Extension

public interface CacheTopologyValidatorProvider
extends Extension

The CacheTopologyValidatorProvider is used to pass an implementation of TopologyValidators for a specific cache through Ignite plugin extensions mechanism. Each cache, on startup, iterates over all registered CacheTopologyValidatorProviders and tries to obtain the instance of TopologyValidator by cache name. All obtained TopologyValidators are saved in the cache context and successively called during topology validation process. The topology validation is passed if all TopologyValidators consider that the current topology is valid.
