Method Detail- 
isApplicablepublic boolean isApplicable(FunctionCallGraph fgraph) Indicates if an IPA pass is applicable for the current configuration. The configuration depends on OptimizerUtils.FEDERATED_COMPILATION.- Specified by:
- isApplicablein class- IPAPass
- Parameters:
- fgraph- function call graph
- Returns:
- true if federated compilation is activated.
 
 - 
rewriteProgrampublic boolean rewriteProgram(DMLProgram prog, FunctionCallGraph fgraph, FunctionCallSizeInfo fcallSizes) Estimates cost and selects a federated execution plan by setting the federated output value of each hop in the program.- Specified by:
- rewriteProgramin class- IPAPass
- Parameters:
- prog- dml program
- fgraph- function call graph
- fcallSizes- function call size infos
- Returns:
- false since the function call graph never has to be rebuilt
