Class and Description
AbstractBlockStoreEventListener A block store event listener base class implementing the BlockStoreEventListener interface with empty methods bodies.
BlockMetadataEvictorView This class exposes a narrower view of BlockMetadataManager to Evictors, filtering out un-evictable blocks and un-allocatable space internally, so that evictors and allocators can be developed with much simpler logic, without worrying about various constraints, e.g.
BlockStoreEventListener A listener interface for receiving metadata mutation events of BlockStore.
BlockStoreLocation Where to store a block within a block store.
