For fetching data from datastore via primary key using JDO, Is there any performance difference between
PersistenceManager pm = PMF.get().getPersistenceManager(); Employee e = pm.getObjectById(Employee.class, user.getEmail()); and PersistenceManager pm = PMF.get().getPersistenceManager(); String query = "select from " + Employee.class.getName() + " where ID == '" + user.getEmail + "'"; List<Employee> eList = (List<Employee>) pm.newQuery(query).execute(); Employee e = eList.get(0); ID is the primary key for entity class Employee.
