Class FederatedMemoTable

java.lang.Object

org.apache.sysds.hops.fedplanner.FederatedMemoTable

public class FederatedMemoTable
extends Object

A Memoization Table for managing federated plans (FedPlan) based on combinations of Hops and fedOutTypes. This table stores and manages different execution plan variants for each Hop and fedOutType combination, facilitating the optimization of federated execution plans.
