- Automatically increases DB storage capacity when usage approaches the allocated limit.
- Eliminates the need for manual scaling.
- You define a Maximum Storage Threshold to limit growth.
- Trigger conditions:
- Free storage < 10% of allocated capacity.
- Low-storage condition persists for ≥ 5 minutes.
- At least 6 hours since the last scaling event.
- Works with all RDS engines.
- Ideal for unpredictable workloads.
