Cluster table for large data

What causes this issue?

If this option is selected, cache entries with query data that exceed
the predefined size limit when initially created are written to the
cluster table (also known as index table). It is not beneficial to use
cluster tables when transporting larger data volumes between the
database and application server because this requires multiple implicit
SELECTS. However, it is possible to save in internal tables; this means
that the data export can take place in an internal table instead of an
XSTRING, which offers better performance under some circumstances.
