All Implemented Interfaces:

public class ReduceTableWrapper
extends org.gridgain.internal.h2.table.Table

Thread local table wrapper for real reducer table. All reduce queries share the same small set of this fake tables. During reduce query execution every thread installs it's own real reduce tables into thread-local storage.
