AWS opensearch-service documentation change
Summary
Added documentation section about EBS metric increases during volume resizing with operational recommendations
Security assessment
The change adds guidance about expected EBS metric behavior during volume resizing and operational best practices. While it addresses availability considerations, there is no evidence of addressing a security vulnerability or documenting security-specific features.
