Class AbstractMutableVirtualTable

java.lang.Object

org.apache.cassandra.db.virtual.AbstractVirtualTable

org.apache.cassandra.db.virtual.AbstractMutableVirtualTable

All Implemented Interfaces:

VirtualTable

public abstract class AbstractMutableVirtualTable
extends AbstractVirtualTable

An abstract virtual table implementation that builds the resultset on demand and allows fine-grained source modification via INSERT/UPDATE, DELETE and TRUNCATE operations. Virtual table implementation need to be thread-safe has they can be called from different threads.
