Pre-fetching allows the agent to cache specified secrets or those matching tag values during startup, minimizing application startup delays by batching secret retrieval instead of sequential calls. IAM role assumption lets the agent assume a defined role to retrieve secrets, enabling secure cross-account secret access without custom logic.
Together, these improvements streamline secret management workflows, enhance security posture by leveraging role-based permissions, and reduce operational complexity across all AWS Regions where Secrets Manager is available.
