Class MConnectionFactory

Object

MConnectionFactory

public class MConnectionFactory
extends Object

The MConnectionFactory provides exactly the same static methods as those provided by the standard HBase ConnectionFactory, but a Connection object created by the MConnectionFactory generates special Admin, Table, and BufferedMutator objects which, in addition to providing all standard HBase API functionality, also: (a) transparently interface with the ColumnManager repository for tracking of Namespace, Table, Column Family, and ColumnAuditor metadata, and (b) optionally enforce administrator-specified ColumnDefinitions when Columns are submitted in a put (i.e., insert/update) via Table, BufferedMutator, and HTableMultiplexer interfaces.
