Hi ,
My datastore Update takes time to reflect in datastore.
We use two way to persist our updated object in datastore both works for us.
Option 1. :- Get the object form the datastore detached the same and send
the json as response . We do the changes in json properties in front-end
and pass the same to update the completer object like this.
try{
pm = PersistenceManagerUtil.getPersistanceManager();
pm.makePersistent(object);
}catch(Exception e){
}finally{
pm.close();
}
The got the info form documentation that
The call to makePersistent() is synchronous, and doesn't return until the
object is saved and indexes are updated.
Here my question is as i am update the whole Object does it indexes all the
filed again which is the cause of the delay in datastore update.
Option 2:
We Just pass the Id or key form the front end and then use
Employee e = pm.getObjectById(Employee.class, k);
WE update the e properties with change value the
pm.makePersistent(e);
}catch(Exception e){
}finally{
pm.close();
}
Fell like doing two step but does work little fast . sometime can't say .
My question here is is there any difference between option 1 and option 2
if not what is the appropriate solution for making it fast .
