 * Simplified circuit breaker implementation for SMB operations.
 * Thread-safe and lock-free implementation to prevent cascading failures.
 *
 * Features:
 * - Simple state management (CLOSED, OPEN, HALF_OPEN)
 * - Lock-free atomic operations
 * - Configurable thresholds and timeouts

 *
 * <p>The {@link org.apache.maven.api.Session} interface is the main entry point for Maven operations.
 * It maintains the state of a Maven execution and provides access to all core services and components.
 * Sessions are thread-safe and can be obtained in session-scoped components using the
 * {@link org.apache.maven.api.di.SessionScoped} annotation.</p>
 *
 * <p>Key capabilities provided through the Session include:</p>

### High availability

A stand-alone MinIO server would go down if the server hosting the drives goes offline. In contrast, a distributed MinIO setup with _m_ servers and _n_ drives will have your data safe as long as _m/2_ servers or _m*n_/2 or more drives are online.
