global class BatchArchiveKB implements Database.Batchable<SObject> {
    global string query;

    global BatchArchiveKB() {
        Map<String, ArchiveKB__mdt> mapCMD = ArchiveKB__mdt.getAll();
    
    }

    global Database.QueryLocator start(Database.BatchableContext BC){
         ArchiveKB__mdt[] KBids = [Select Id, Salesforce_ID__c from ArchiveKB__mdt];
          Set<String> sfid = new Set<String>();
              for(ArchiveKB__mdt record:KBids) {
                  sfid.add(record.Salesforce_ID__c);
            }
        System.debug('sfids'+sfid);
         return Database.getQueryLocator([Select Id, KnowledgeArticleId FROM Customer_Support__kav WHERE ID =:sfid]);
  
    }
            
    global void execute(Database.BatchableContext BC, List<Customer_Support__kav> todelete) {
        system.debug('Todelete'+todelete);
        for (Customer_Support__kav kav:  todelete)
        {
            KbManagement.PublishingService.archiveOnlineArticle(kav.knowledgeArticleId,null);
             System.debug(kav.Id);
        }   
       
    }
     global void finish(Database.BatchableContext bc){
    
    }
