To get started writing a controller, review the [Example Controller](../../pkg/kube/controllers/example_test.go).

### Controllers overview

Below provides a high level overview of controllers in Istiod. For more information about each controller, consulting the controllers Go docs is recommended.

### OpenAPI

**FastAPI** generuje "schemat" z całym Twoim API przy użyciu standardu **OpenAPI** służącego do definiowania API.

#### Schema

"Schema" jest definicją lub opisem czegoś. Nie jest to kod, który go implementuje, ale po prostu abstrakcyjny opis.

#### API "Schema"

- Choosing an erasure set for the object is decided during `PutObject()`, object names are used to find the right erasure set using the following pseudo code.

```go
// hashes the key returning an integer.
func sipHashMod(key string, cardinality int, id [16]byte) int {
        if cardinality <= 0 {
                return -1
        }
        sip := siphash.New(id[:])

### Debug metrics

Standard Go runtime metrics from the [Prometheus Go Client base collector](https://github.com/prometheus/client_golang).

| Path        | Description         |
|-------------|---------------------|
| `/debug/go` | Go runtime metrics. |

### ILM metrics

Metrics about the MinIO ILM functionality.

FastAPI is a modern, fast (high-performance), web framework for building APIs with Python based on standard Python type hints.

The key features are:

* **Fast**: Very high performance, on par with **NodeJS** and **Go** (thanks to Starlette and Pydantic). [One of the fastest Python frameworks available](#performance).
* **Fast to code**: Increase the speed to develop features by about 200% to 300%. *

- DeleteMarker (a versionId to capture the DELETE sequences implemented primarily for AWS spec compatibility)

A sample msgpack-JSON `xl.meta`, you can debug the content inside `xl.meta` using [xl-meta.go](https://github.com/minio/minio/tree/master/docs/debugging#decoding-metadata) program.
