Ce n'est pas un hasard, ce framework entier a été bâti avec ce design comme objectif.

You also get error checks for incorrect type operations:

This is not by chance, the whole framework was built around that design.

This document focuses on showing a working example on how to use Object Lambda with MinIO, you must have [MinIO deployed in your environment](https://docs.min.io/community/minio-object-store/operations/installation.html) before you can start using external lambda functions. You also must install Python version 3.8 or later for the lambda handlers to work.

## Example Lambda handler

Install the necessary dependencies.
```sh

        for (int i = 0; i < THREAD_COUNT; i++) {
            final int index = i;
            threads[i] = new Thread(() -> {
                try {
                    // Each thread performs operations on the response
                    byte[] buffer = new byte[100];
                    response.writeSetupWireFormat(buffer, 0);
                    response.readParametersWireFormat(buffer, 0, 100);

variables as part of those interactions (ex: using a string variable to build a
filesystem path), a maliciously created checkpoint might be able to change the
targets of those operations, which could result in arbitrary
read/write/executions.

No Python 3.10 também existe uma **nova sintaxe** onde você pode colocar os possíveis tipos separados por uma <abbr title='também chamado de "bitwise ou operador", mas o significado é irrelevante aqui'>barra vertical (`|`)</abbr>.
