Detailed Description

Abstract interface for metrics storage.

Provides persistence capabilities for metric snapshots. Implementations can store data in memory, on disk, or in external databases.

Thread Safety:

Implementations MUST be thread-safe. Store and retrieve operations may be called concurrently.
