All Superinterfaces:

one.microstream.persistence.types.PersistenceObjectIdAcceptor

All Known Implementing Classes:

StorageEntityMarkMonitor.Default

public interface StorageEntityMarkMonitor
extends one.microstream.persistence.types.PersistenceObjectIdAcceptor

Central instance serving as a locking instance (concurrency monitor) for concurrently marking entities. Via the indirection over a pure OID (long primitives) mark queue, the actual marking, sweeping and concurrency management associated with it is strictly thread local, like the rest of the storage implementation is. Without that centralization and indirection, absolute concurrency correctness is hard to achieve and much more coding effort.
