Proposed Rule Name: [apex] Avoid Stateful Database Results
Proposed Category: Error Prone
Description: Instance variables of type Database.[x]Result can cause serialization issues between successive batch iterations when used in an implementation of the Database.Stateful interface. Please avoid using such variables unless they are transient.
This helps to avoid this known issue
Code Sample:
public class Example implements Database.Batchable, Database.Stateful {
Database.SaveResult[] results; // this can cause failures
public Database.Querylocator start(Database.BatchableContext context){
return Database.getQueryLocator('SELECT Id FROM Account LIMIT 10');
}
public void execute(Database.BatchableContext context, List<SObject> scope){
results = Database.update(scope, false);
}
public void finish(database.BatchableContext context){
}
}
