ROS (Read Optimized Store)

Read Optimized Store (ROS) is a highly optimized, read-oriented, disk storage structure, organized by projection. ROS makes heavy use of compression and indexing.

The Tuple Mover is the Vertica database optimizer component that moves data from memory (WOS) to disk (ROS). The Tuple Mover runs in the background, performing tasks automatically at time intervals determined by its configuration parameters.
