通过从一个配置跳跃到一个差异巨大的配置，然后再进行细小的调整来让能量最小化，罗塞塔算法以此来处理其需要扫描的这巨大的能量图景。

The Rosetta algorithm handles the huge energy landscape it needs to scan by taking big leaps between different configurations, then attempting to minimize the energy by making smaller tweaks.

Time 维度表中满足过滤条件的 time_id 连接键被散列以创建一个位向量，用于过滤以上跳跃式扫描的 Orders 表行。

The time_id join keys that meet the filter requirements on the Time dimension table are hashed to create a bit vector that filters rows of the Orders table from the skip scan above.

对于多索引下推，多索引扫描用于组合来自不同索引扫描的RID，然后就可以执行对事实表的跳跃式扫描了。

For multiple index push-downs, multi-index scan is used to combine RIDs from different index scans, then skip-scan on the fact table is performed.
