/**
 * Implementation of IndexUpdateCallback that handles file list index updates with concurrent processing.
 * This callback processes file events (create, modify, delete) and manages document indexing and deletion

 * <p>The implementation uses an executor service for concurrent processing of file operations and maintains

Ein **Kontextmanager** in Python ist etwas, das Sie in einer `with`-Anweisung verwenden können, zum Beispiel kann `open()` als Kontextmanager verwendet werden:

```Python
with open("file.txt") as file:
    file.read()
```

In neueren Versionen von Python gibt es auch einen **asynchronen Kontextmanager**. Sie würden ihn mit `async with` verwenden:

```Python
async with lifespan(app):
    await do_stuff()
```
