MinIO is a high performance distributed object storage server, designed for large-scale private cloud infrastructure. MinIO is designed in a cloud-native manner to scale sustainably in multi-tenant environments. Orchestration platforms like Kubernetes provide perfect cloud-native environment to deploy and scale MinIO.

## MinIO Deployment on Kubernetes

There are multiple options to deploy MinIO on Kubernetes:

		rs:        ReplicationState{ReplicationStatusInternal: "arn1=PENDING;", Targets: map[string]replication.StatusType{"arn1": "PENDING"}},
		expStatus: replication.Pending,
	},
	{ // 3. replication status for one target - incorrect format
		name:      "replication status for one target",
		rs:        ReplicationState{ReplicationStatusInternal: "arn1=PENDING"},
		expStatus: replication.StatusType(""),
	},

func TestParseRestoreObjStatus(t *testing.T) {
	testCases := []struct {
		restoreHdr     string
		expectedStatus restoreObjStatus
		expectedErr    error
	}{
		{
			// valid: represents a restored object, 'pending' expiry.
			restoreHdr: `ongoing-request="false", expiry-date="Fri, 21 Dec 2012 00:00:00 GMT"`,
			expectedStatus: restoreObjStatus{
				ongoing: false,
				expiry:  time.Date(2012, 12, 21, 0, 0, 0, 0, time.UTC),
			},

			srs.Latency.update(st.TransferSize, st.TransferDuration)
			srs.updateXferRate(st.TransferSize, st.TransferDuration)
		}
	case st.Failed:
		srs.Failed.addsize(st.TransferSize, st.Err)
	case st.Pending:
	}
	sr.M[dID] = srs
}

func (sr *SRStats) get() map[string]SRMetric {
	epMap := globalBucketTargetSys.healthStats()

	sr.lock.RLock()
	defer sr.lock.RUnlock()

	}
}

func (z *erasureServerPools) decommissionInBackground(ctx context.Context, idx int) error {
	pool := z.serverPools[idx]
	z.poolMetaMutex.RLock()
	pending := z.poolMeta.PendingBuckets(idx)
	z.poolMetaMutex.RUnlock()

	for _, bucket := range pending {
		z.poolMetaMutex.RLock()
		isDecommissioned := z.poolMeta.isBucketDecommissioned(idx, bucket.String())
		z.poolMetaMutex.RUnlock()
		if isDecommissioned {

// - replicated size for all objects sent to this target
// - replica size for all objects received from this target
// - replication pending size for all objects pending replication to this target
// - replication failed size for all objects failed replication to this target
// - replica pending count
// - replica failed count
type BucketTargetUsageInfo struct {
	ReplicationPendingSize  uint64 `json:"objectsPendingReplicationTotalSize"`

			b.updateXferRate(rs.TransferSize, rs.TransferDuration)
		}
	case rs.Failed:
		b.FailStats.addsize(rs.TransferSize, rs.Err)
	case rs.Pending:
	}
}

type replStat struct {
	Arn       string
	Completed bool
	Pending   bool
	Failed    bool
	opType    replication.Type
	// transfer size
	TransferSize int64
	// transfer duration
	TransferDuration time.Duration

		return false
	}
}

func (m *muxClient) close() {
	if debugPrint {
		fmt.Println("closing outgoing mux", m.MuxID)
	}
	if !m.respMu.TryLock() {
		// Cancel before locking - will unblock any pending sends.
		if m.cancelFn != nil {
			m.cancelFn(context.Canceled)
		}
		// Wait for senders to release.
		m.respMu.Lock()
	}

	defer m.respMu.Unlock()
	m.closeLocked()
}

MinIO is built ground up on the cloud-native premise. With features like erasure-coding, distributed and shared setup, it focuses only on storage and does it very well. While, it can be scaled by just replicating MinIO instances per tenant via an orchestration platform.

	IsLatest bool `msg:"is"`

	// Deleted is set when this FileInfo represents
	// a deleted marker for a versioned bucket.
	Deleted bool `msg:"del"`

	// TransitionStatus is set to Pending/Complete for transitioned
	// entries based on state of transition
	TransitionStatus string `msg:"ts"`
	// TransitionedObjName is the object name on the remote tier corresponding
	// to object (version) on the source tier.
