Hi all. Is there a person who has dissatisfaction in current JDO? Do not you think that the solution is low-level API?
When JDO is used, it is easy for us who become accustomed to the O/R mapping possibly. You might think solving. I think that I am also certainly easy. However, I think that it is a trap. When JDO is used to some degree, the limit is sure to be seen. It tries to apply the specification made for RDBMS to a different Key-Value type data store by force originally. And, do you really solve it? I think that I should grope for the specification and the method of agreement to it in the Key-Value type data store. In JDO and low-level API, the performance is also different at all. JDO high performance certainly. However, there is still a lot of trouble in JDO. Low-level API is a low function like the name. However, low-level API is simple and low the study cost. Moreover, the performance is high, and mysterious existence to seem to teach us a mystery the data store original. Naturally, the rapper that covers low-level API is needed. Do not you misinterpret it though original architecture is different? DLL hell, XML hell, and annotation hell. My anxiety is to become a nest hell. I think that I should deepen the discussion more. To begin with, the aspect of API design that is appropriate for the Key-Value type data store is also necessary. Even if the individual (one) says dissatisfaction, it is likely to be disregarded. However, if everyone thinks like that, it becomes a request of the market. I'm sorry in poor English. This is an automatic translation. -- ----------------------------------------------------------- Kazuki Aranam） Email: kazuki.aran...@gmail.com http://d.hatena.ne.jp/kazuki-aranami/ ----------------------------------------------------------- --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.
