Option
Specifies the maximum number of Btree pages used in evaluating a range predicate in the HG index.
Integer
10
Option can be set at the database (PUBLIC) or user level. At the database level, the value becomes the default for any new user, but has no impact on existing users. 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 setting of this option is appropriate for most queries.
This option effectively controls the amount of time the optimizer spends searching for the best index to use for a range predicate. Setting this option higher may cause a query to spend more time in the optimizer, but as a result may choose a better index to resolve a range predicate.
