Specifies degree of parallelism used in the default index.
Option can be set at the database (PUBLIC) or user level. When set at the database level, the value becomes the default for any new user, but has no impact on existing users. When set at the user level, overrides the PUBLIC value for that user only. No system privilege is required to set option for self. System privilege is required to set at database level or at user level for any user other than self.
Requires the SET ANY PUBLIC OPTION system privilege to set this option. Can be set temporary for an individual connection or for the PUBLIC role. Takes effect immediately.
The default index calculates some predicates such as SUM, RANGE, MIN, MAX and COUNT DISTINCT in parallel. FP_PREDICATE_WORKUNIT_PAGES affects the degree of parallelism used by specifying the number of pages worked on by each thread. To increase the degree of parallelism, decrease the value of this option.
