如前所述，Hibernate就不受支持(主要是因为使用App Engine时，您无法拥有关系数据库)。
As I mentioned, Hibernate can't be used (mainly because with the App Engine you don't have a relational database).
如前所述，可以直接释放没有经过修改的永久存储分页，无需将其写入到文件系统中，因为文件系统包含该数据的原始副本。
As mentioned earlier, an unmodified permanent storage page can just be released without being written to the file system, since the file system contains a pristine copy of the data.
然而，如前所述，这一点不必担心，因为一旦出现下一次日志切换，受影响的逻辑日志将由ALARMPROGRAM保存起来。
However, as already mentioned, there is no need to worry about this because the affected logical log will be saved by the ALARMPROGRAM as soon as the next log switch occurs.
