Explanation
To help the system recover from a maintenance restart on Salesforce servers, the Salesforce feature that would help is enabling deferred sharing rule recalculation. This feature allows postponing the recalculation of sharing rules until a scheduled time, which can improve performance and avoid locking issues when there are frequent changes to sharing rules or role hierarchy5. Enabling granular locking or parallel sharing rule recalculation will not help, as they are related to improving performance and avoiding locking issues when recalculating sharing rules, not recovering from a maintenance restart. Enabling filter-based opportunity territory assignment will not help, as it is related to assigning opportunities to territories based on criteria, not recovering from a maintenance restart.
