Time, in seconds, before a multiplex DQP leader reassigns incomplete distributed work to another DQP worker node.
DQP work units are typically sized to span only a few seconds. If a worker node goes offline or experiences an unusually high workload, DQP work previously assigned to that worker node is reassigned to another node after the given timeout.
60 seconds
Typically you do not need to change this option from its default value. However, increase this option in rare cases where a query has very large intermediate results that cause individual work units to time out.
Decrease this option if unreliable networks or servers cause distributed work to be lost and the timeout interval is unacceptably long. Note that setting this option too low can cause unnecessary early timeouts.
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.
