DB2 row compression features can decrease disk storage requirements while at the same time improve sequential read access of large queries which perform full table scans.
DB 2行压缩功能可以减少磁盘存储需求，同时改进执行全表扫描的大量查询的顺序读取访问。
It's also optimized for full table scans (one of the most common-and most time-consuming-business intelligence query access patterns).
它还针对完全表扫描(一个最常见—也最耗时—的商业智能查询访问模式)进行了优化。
After the table is redistributed (the table goes back to the normal state), you are required to take a tablespace level backup in order to acquire full access to the table again.
在这个表被重分发之后(回到正常状态)，需要进行一个表空间级的备份，以便重新获得对该表的全部访问权。
