[Figure: Overview of RANDOM structure]
RANDOM structure features for data processing patterns
The factor having the greatest effect on data processing efficiency is the I-O frequency. The RANDOM structure has
the following features:
· If all values of the cluster key are specified in conditional expressions and a unique constraint is set as the
cluster key in data processing, the I/O frequency hardly depends on the data volume.
· In other cases, since all data is referenced, the I-O frequency depends greatly on the data volume. In these
