GRANULARITY
Determines the granularity of statistics to collect. This value is only relevant for partitioned tables.
参数可选项:
GRANULARITY - The value determines granularity of statistics to collect (only pertinent if the table is partitioned).
‘ALL‘ - gathers all (subpartition,partition,and global) statistics
‘AUTO‘ - determines the granularity based on the partitioning type. This is the default value.
‘DEFAULT‘ - gathers global and partition-level statistics. This option is obsolete,and while currently supported,it is included in the documentation for legacy reasons only. You should use the ‘GLOBAL AND PARTITION ‘ for this functionality. Note that the default value is now ‘AUTO ‘.
‘GLOBAL‘ - gathers global statistics
‘GLOBAL AND PARTITION ‘ - gathers the global and partition level statistics. No subpartition level statistics are gathered even if it is a composite partitioned object.
‘PARTITION ‘- gathers partition-level statistics
‘SUBPARTITION‘ - gathers subpartition-level statistics.
