type Handler 

type Handler interface {
	Handle(ctx context.Context, header *protocol.RequestHeader, req protocol.Request) ([]byte, error)

}

S3HealthConfig defines thresholds for transitioning between states.

type S3HealthMonitor 

type S3HealthMonitor struct {
	// contains filtered or unexported fields
}

S3HealthMonitor aggregates recent S3 requests to determine a health state.

func NewS3HealthMonitor 

func NewS3HealthMonitor(cfg S3HealthConfig) *S3HealthMonitor

NewS3HealthMonitor builds a health monitor with sane defaults.

func (*S3HealthMonitor) RecordOperation 

func (m *S3HealthMonitor) RecordOperation(op string, latency time.Duration, err error)

RecordOperation records an arbitrary S3 operation outcome.

func (*S3HealthMonitor) RecordUpload 

func (m *S3HealthMonitor) RecordUpload(latency time.Duration, err error)

RecordUpload remains for backward compatibility.

func (*S3HealthMonitor) Snapshot 

func (m *S3HealthMonitor) Snapshot() S3HealthSnapshot

Snapshot returns the current state and key aggregates.

func (*S3HealthMonitor) State 

func (m *S3HealthMonitor) State() S3HealthState

State returns just the current health state.

type S3HealthSnapshot 

type S3HealthSnapshot struct {
	State      S3HealthState
	Since      time.Time
	AvgLatency time.Duration
	ErrorRate  float64

S3HealthSnapshot captures the monitor's public metrics.

type S3HealthState 

type S3HealthState string

S3HealthState models the broker's view of S3 availability. 

const (
	S3StateHealthy     S3HealthState = "healthy"
	S3StateDegraded    S3HealthState = "degraded"
	S3StateUnavailable S3HealthState = "unavailable"
)

type Server 

type Server struct {
	Addr    string
	Handler Handler
	// contains filtered or unexported fields
