Class ProcessDistributorImpl

java.lang.Object

fr.gouv.vitam.processing.distributor.v2.ProcessDistributorImpl

All Implemented Interfaces:

ProcessDistributor, AutoCloseable

public class ProcessDistributorImpl
extends Object
implements ProcessDistributor

The Process Distributor call the workers and intercept the response for manage a post actions step

 TODO P1:
 - handle listing of items through a limited arraylist (memory) and through iterative (async) listing from
 Workspace
 - handle result in FATAL mode from one distributed item to stop the distribution in FATAL mode (do not
 continue)
 - try to handle distribution on 1 or on many as the same loop (so using a default arrayList of 1)
 - handle error level using order in enum in ProcessResponse.getGlobalProcessStatusCode instead of manually comparing:
  
    for (final EngineResponse response : responses) {
       tempStatusCode = response.getStatus();
       if (statusCode.ordinal() > tempStatusCode.ordinal()) {
           statusCode = tempStatusCode;
       }
      if (statusCode.ordinal() > StatusCode.KO.ordinal()) {
           break;
       }
     }
