Class MaterializedViewManager

java.lang.Object

org.apache.cassandra.db.view.MaterializedViewManager

public class MaterializedViewManager
extends java.lang.Object

Manages MaterializedView's for a single ColumnFamilyStore. All of the materialized views for that table are created when this manager is initialized. The main purposes of the manager are to provide a single location for updates to be vetted to see whether they update any views updateAffectsView(PartitionUpdate), provide locks to prevent multiple updates from creating incoherent updates in the view acquireLockFor(ByteBuffer), and to affect change on the view.
