global Database.QueryLocator start(Database.BatchableContext BC) {

     

  queryString = 'SELECT Id, Name, Email FROM Lead ';

    return Database.getQueryLocator(queryString);

}

  global void execute(Database.BatchableContext BC, List<Lead> obj) {

Map<String,List<Lead>> LeadMap = new Map<String,List<Lead>>();

  Set<String> LeadName = new Set<String>();

  Set<String> LeadEmail = new Set<String>();

  

  for(Lead a :obj){

     LeadName.add(a.Name.toLowerCase());

      if(String.isnotblank(a.Email))

     LeadEmail.add(a.Email.toLowerCase());

     

  }

  //Get All non formula fields of Lead

  String sobjectApiName = 'Lead';

  Map<String, Schema.SObjectType> schemaMap = Schema.getGlobalDescribe();

  Map<String, Schema.SObjectField> fieldMap = schemaMap.get(SobjectApiName).getDescribe().fields.getMap();

  List<String> fieleList = new List<String>();

  for(String fieldName : fieldMap.keySet()){

     Schema.DescribeFieldResult fieldResult = fieldMap.get(fieldName).getDescribe();

     if(!fieldResult.isCalculated() && fieldResult.isCreateable() && !fieldResult.isExternalId()&& fieldResult.isUpdateable()){

        fieleList.add(fieldName);

     }

     /*if(fieldName != 'isPartner' && fieldName != 'IsCustomerPortal'){

        fieleList.add(fieldName);

     }*/

  }

  String fetchFields = 'SELECT '+String.join(fieleList,',')+' FROM '+sobjectApiName+' WHERE Email IN :LeadEmail';

  integer i = 1;

  for(Lead a : Database.query(fetchFields)){

     String key = a.Email;

     key = key.toLowerCase();

     if(LeadMap.containsKey(key)){

        LeadMap.get(key).add(a);

     }else {

        LeadMap.put(key,new List<Lead>{a});

     }

     i++;

  }

  System.debug('i >'+i);

System.debug('LeadMap >> '+LeadMap);

  List<Lead> mergeList;

for(String key : LeadMap.keySet()){

     System.debug('Size >>'+ LeadMap.get(key).size());

    if(LeadMap.get(key).size()>1 ){

        mergeList = new List<Lead>();

        Lead masterLead = LeadMap.get(key)[0];

        mergeList.addAll(LeadMap.get(key));

        mergeList.remove(0);

        System.debug('mergeList >> '+mergeList);

        for(Lead a : mergeList){

            Database.MergeResult mergeResult = Database.merge(masterLead, a, true);

        } 

    }

}

//if(mergeList.size()>0)

//  update mergeList;

}

global void finish(Database.BatchableContext BC) {

}
