Cluster

A cluster is a set of tables, physically stored together as one table that shares a common columns. If data in two or more tables are frequently retrieved together based on data in the common column, using a cluster can be quite efficient. Tables can be accessed separately even though they are part of a cluster. Because of the structure of the cluster, related data requires much less input/output (I/O) overhead if accessed simultaneously.
