SUMMARY_STAT_USER_TABLES

Displays the sum of the status information about user-defined ordinary tables in all schemas of a cluster. It is used on the CN. The status information about user-defined ordinary tables on each DN is summed up. The timestamp column is not summed up and only the latest value of this column on all nodes is used, as described in Table 1.
