### 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

// May or may not send an update upstream.
func (f *folderScanner) sendUpdate() {
	// Send at most an update every minute.
	if f.updates == nil || time.Since(f.lastUpdate) < time.Minute {
		return
	}
	if flat := f.updateCache.sizeRecursive(f.newCache.Info.Name); flat != nil {
		select {
		case f.updates <- flat.clone():
		default:
		}

		globalBucketTargetSys.set(buckets[i], meta) // set remote replication targets
	}
}

func (sys *BucketMetadataSys) refreshBucketsMetadataLoop(ctx context.Context) {
	const bucketMetadataRefresh = 15 * time.Minute

	sleeper := newDynamicSleeper(2, 150*time.Millisecond, false)

	t := time.NewTimer(bucketMetadataRefresh)
	defer t.Stop()
	for {
		select {
		case <-ctx.Done():
			return
		case <-t.C:
