AWS redshift documentation change

Service: redshift · 2025-12-07 · Documentation low

File: redshift/latest/mgmt/example_redshift_CreateCluster_section.md

Summary

Added .NET SDK v4 code example for CreateCluster API including master user credentials handling

Security assessment

The change adds a code example demonstrating cluster creation with master username/password parameters, but does not address any specific security vulnerability or weakness. While credentials handling is security-sensitive, this is standard API usage documentation rather than security guidance or vulnerability mitigation.
