在清单5中,我们在调用期间动态地构建了数组引用,然后在打印结果时使用OID作为散列键。
In Listing 5 we build the array reference dynamically during the call, and then use the OID as the hash key when printing out the result.
例如,如果键是整数,该值应该作为散列码。
For example, if the key is an integer, this value might serve as the hash code.
通过对上述两个表的连接键(pdb_id)进行散列处理来分布两个表也能确保给定pdbml文档中所有原子行均能作为本身的PDBML文档存储在相同的数据库分区中。
Distributing both tables by hashing on their join key (pdb_id) also ensures that all atom rows for a given PDBML document are stored in the same database partition as the PDBML document itself.
