## Example Lambda handler

Install the necessary dependencies.
```sh
pip install flask requests
```

Following is an example lambda handler.
```py
from flask import Flask, request, abort, make_response
import requests

app = Flask(__name__)

    protected int maxDocumentCacheSize;

    /** Factory for creating ingesters to process documents */
    private IngestFactory ingestFactory = null;

    /**
     * Initializes the callback implementation after dependency injection.
     * Sets up configuration values and initializes the ingest factory if available.
     */
    @PostConstruct
    public void init() {
        if (logger.isDebugEnabled()) {

### Abhängigkeiten

Das Gleiche gilt für [Abhängigkeiten](tutorial/dependencies/index.md){.internal-link target=_blank}. Wenn eine Abhängigkeit eine normale `def`-Funktion ist, anstelle einer `async def`-Funktion, dann wird sie im externen Threadpool ausgeführt.

### Unterabhängigkeiten

#### 6.3 Integration Points
- Integrate with `CIFSContext` for witness support
- Modify `SmbTransport` for failover handling
- Update `DfsResolver` for witness-aware resolution

/// tip

If you need to do any type of validation that requires communicating with any **external component**, like a database or another API, you should instead use **FastAPI Dependencies**, you will learn about them later.

These custom validators are for things that can be checked with **only** the **same data** provided in the request.
