Partitioning a Relation across Disks If a relation contains only a few tuples which will fit into a single disk block,then assign the relation to a single disk. Large relations are preferably partitioned across all the available disks. If a relation consists of m disk blocks and there are n disks available in the system,then the relation should be allocated min(m,n)disks.
