**Key Capabilities:**
- Full-text search with OpenSearch backend
- Web, file system, and data store crawling
- Multi-format document support (Office, PDF, etc.)
- Admin GUI for configuration
- REST API for programmatic access
- SSO integration (OIDC, SAML, SPNEGO, Entra ID)

scanner (which runs at one minute intervals, each time scanning one sixteenth of the namespace), picks up the object for tiering. The data is moved to the remote tier in entirety, leaving only the object metadata on MinIO.

The data on the backend is stored under the `bucket/prefix` specified in the tier configuration with a custom name derived from a randomly generated uuid - e.g. `0b/c4/0bc4fab7-2daf-4d2f-8e39-5c6c6fb7e2d3`. The first two prefixes are characters 1-2,3-4 from the uuid. This...

어떤 도메인에 **backend** API가 있다고 가정해 보겠습니다.

그리고 다른 도메인에 **frontend**가 있거나, 같은 도메인의 다른 경로에 있거나(또는 모바일 애플리케이션에 있을 수도 있습니다).

그리고 frontend가 **username**과 **password**를 사용해 backend에 인증할 수 있는 방법이 필요하다고 해봅시다.

**FastAPI**와 함께 **OAuth2**를 사용해서 이를 구현할 수 있습니다.

하지만 필요한 작은 정보 조각들을 찾기 위해 길고 긴 전체 스펙을 읽느라 시간을 쓰지 않도록 하겠습니다.

보안을 처리하기 위해 **FastAPI**가 제공하는 도구들을 사용해 봅시다.

## 어떻게 보이는지 { #how-it-looks }

// Filter - a filter for a replication configuration Rule.
type Filter struct {
	XMLName xml.Name `xml:"Filter" json:"Filter"`
	Prefix  string
	And     And
	Tag     Tag

	// Caching tags, only once
	cachedTags map[string]string
}

// IsEmpty returns true if filter is not set
func (f Filter) IsEmpty() bool {
	return f.And.isEmpty() && f.Tag.IsEmpty() && f.Prefix == ""
}

Schauen wir uns an, wie wir das machen können.

Being able to use asynchronous functions in your tests could be useful, for example, when you're querying your database asynchronously. Imagine you want to test sending requests to your FastAPI application and then verify that your backend successfully wrote the correct data in the database, while using an async database library.

Let's look at how we can make that work.

## pytest.mark.anyio { #pytest-mark-anyio }

	migrateDataDir := mustGetUUID()

	if !latestMeta.Deleted && len(latestMeta.Erasure.Distribution) != len(onlineDisks) {
		err := fmt.Errorf("unexpected file distribution (%v) from online disks (%v), looks like backend disks have been manually modified refusing to heal %s/%s(%s)",
			latestMeta.Erasure.Distribution, onlineDisks, bucket, object, versionID)
		healingLogOnceIf(ctx, err, "heal-object-online-disks")

```python
from main import app
```

もしコード構成が次のようになっている場合:

```
.
├── backend
│   ├── main.py
│   ├── __init__.py
```

このときは`entrypoint`を次のように設定します:

```toml
[tool.fastapi]
entrypoint = "backend.main:app"
```

これは次と同等です:

```python
from backend.main import app
```
