You can partition an index-organized table by RANGE, HASH, or LIST on column
values. The partitioning columns must form a subset of the primary key columns. Just
like ordinary tables, local partitioned (prefixed and non-prefixed) index as well as
global partitioned (prefixed) indexes are supported for partitioned index-organized
tables.

分区索引组织表
1. 用户可以采用 RANGE，HASH，或 LIST 的方式对索引表进行分区
2. 分区列必须是属于主键列
3. 可在分区索引表上建立本地全局索引
