Re: [google-appengine] Re: Model.get_by_id performance
Is get_by_key_name as fast as key? or is that slower. What is the best method is the difference marginal?

[google-appengine] Re: Model.get_by_id performance
As I understand, the fastest way is to get by Key because no conversions are needed. Model.get_by_id should be almost the same, because ID+Kind+Path will be converted to Key before querying database. But this operation maybe is too cheap comparing to database seek. Model.get_by_key_name should be the same as Model.get_by_id, because it is the same conversion: Key_name+Kind+Path = Key.
