Class IPAPassRewriteFederatedPlan

  • public class IPAPassRewriteFederatedPlan
    extends IPAPass
    This rewrite generates a federated execution plan by estimating and setting costs and the FederatedOutput values of all relevant hops in the DML program. The rewrite is only applied if federated compilation is activated in OptimizerUtils.

      • isApplicable

        public boolean isApplicable​(FunctionCallGraph fgraph)
        Indicates if an IPA pass is applicable for the current configuration. The configuration depends on OptimizerUtils.FEDERATED_COMPILATION.
        Specified by:
        isApplicable in class IPAPass
        fgraph - function call graph
        true if federated compilation is activated.
