描述

Snapshots contain global state (i.e. parts of the cluster metadata) but the only way you can see what exactly this contains is to restore the snapshot and overwrite the existing cluster state. There's no option to restore only part of the state (e.g. just a specific pipeline or template) nor to compare the state between different snapshots. This would be useful sometimes and would be relatively straightforward to implement.

研究方向
Review the existing snapshot REST API implementation in Elasticsearch (e.g., RestSnapshotAction class). Look at how snapshot metadata is stored and retrieved. Propose a design for a new endpoint that returns global state from a snapshot without restoring it. Consider performance and security implications.
