Configure database parameters
Modify database parameters of your ApsaraDB for MongoDB instance to better suit your business requirements.
Prerequisites
The instance is a standalone, replica set, or sharded cluster instance.
Considerations
Modifying certain parameters automatically restarts the instance. To identify which parameters require a restart, see the Parameter List column on the Force Restart page.
An instance restart interrupts all active connections. Before you modify a parameter that requires a restart, schedule the change during off-peak hours to minimize the impact on your services.
