有一个隐式的假设：每个表中的行是均匀分布在每个多分区数据库分区组中的所有分区上的。
There is an implicit assumption that the rows of each table are evenly distributed across all the partitions in each multiple-partition database partition group.
更改此关系的惟一方式是丢弃此表并在与不同的数据库分区组相关联的一个不同的表空间内重新创建它。
The only way to change this relationship is to drop the table and recreate it in a different table space that is tied to a different database partition group.
标准JPA没有处理分区或分配的有效方式，因为规范已经隐式地假定单个数据库作为存储库。
Standard JPA has no effective means of dealing with sharding or portioning as the specification implicitly assumes a single database as the repository.
