### Just Modern Python

It's all based on standard **Python type** declarations (thanks to Pydantic). No new syntax to learn. Just standard modern Python.

If you need a 2 minute refresher of how to use Python types (even if you don't use FastAPI), check the short tutorial: [Python Types](python-types.md){.internal-link target=_blank}.

You write standard Python with types:

```Python

    protected LoadingCache<ArtifactType, Artifact[]> availableArtifacts = CacheBuilder.newBuilder().maximumSize(10)
            .expireAfterWrite(5, TimeUnit.MINUTES).build(new CacheLoader<ArtifactType, Artifact[]>() {
                @Override
                public Artifact[] load(final ArtifactType key) {
                    final List<Artifact> list = new ArrayList<>();

	}

	if len(poolIndices) > 0 && globalEndpoints[poolIndices[0]].Endpoints[0].IsLocal {
		go func() {
			// Resume decommissioning of pools, but wait 3 minutes for cluster to stabilize.
			if err := sleepContext(ctx, 3*time.Minute); err != nil {
				return
			}
			r := rand.New(rand.NewSource(time.Now().UnixNano()))
			for {
				if err := z.Decommission(ctx, poolIndices...); err != nil {

	rx.sma.addSample(rx.Curr)
	rx.Avg = rx.sma.simpleMovingAvg()
	if rx.Curr > rx.Peak {
		rx.Peak = rx.Curr
	}
	rx.N++
}

// ReplicationMRFStats holds stats of MRF backlog saved to disk in the last 5 minutes
// and number of entries that failed replication after 3 retries
type ReplicationMRFStats struct {
	LastFailedCount uint64 `json:"failedCount_last5min"`

			return s.NewHTTPTransportWithTimeout(1 * time.Minute)
		}
		return transport
	}

	return globalRemoteTargetTransport
}

// NewHTTPTransport returns a new http configuration
// used while communicating with the cloud backends.
func NewHTTPTransport() *http.Transport {
	return NewHTTPTransportWithTimeout(1 * time.Minute)
}

// Default values for dial timeout

	}
	cl.subroute = &c.subID
	return cl, nil
}

// Request allows to do a single remote request.
// 'req' will not be used after the call and caller can reuse.
// If no deadline is set on ctx, a 1-minute deadline will be added.
func (c *Connection) Request(ctx context.Context, h HandlerID, req []byte) ([]byte, error) {
	if !h.valid() {
		return nil, ErrUnknownHandler
	}
	if c.State() != StateConnected {

	saverQuitCh := make(chan struct{})
	go func() {
		saveTicker := time.NewTicker(10 * time.Second)
		defer saveTicker.Stop()
		quit := false
		after := time.Minute
		for !quit {
			select {
			case <-saveTicker.C:
			case <-ctx.Done():
				quit = true
			case <-saverQuitCh:
				quit = true
			}

			if quit {
				// save immediately if we are quitting

		Tiers:       make(map[string]madmin.TierConfig),
	}
}

func (config *TierConfigMgr) refreshTierConfig(ctx context.Context, objAPI ObjectLayer) {
	const tierCfgRefresh = 15 * time.Minute
	r := rand.New(rand.NewSource(time.Now().UnixNano()))
	randInterval := func() time.Duration {
		return time.Duration(r.Float64() * 5 * float64(time.Second))
	}
