Which advanced tool should Salesforce enable for large-scale Role Hierarchy realignments?

Granular Locking:

This feature minimizes record-locking issues by enabling fine-grained locking mechanisms during large-scale operations, such as Role Hierarchy realignments.

It reduces contention by locking only relevant portions of the hierarchy instead of the entire hierarchy.

Why Option A is Correct:

Granular Locking is explicitly designed to handle large-scale operations, such as role realignments, without performance degradation.

Why Others Are Incorrect:

Option B: Skinny Table Indexing improves query performance but is unrelated to Role Hierarchy changes.

Option C: Divisions partition data for performance but do not directly affect Role Hierarchy realignments.
