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

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

    private volatile Thread thread;
    private volatile TransportException te;

    /**
     * Lock object for synchronizing input operations
     */
    protected final Object inLock = new Object();
    /**
     * Lock object for synchronizing output operations
     */
    protected final Object outLock = new Object();

    /**
     * Map for tracking pending responses by their key
     */

        queryContext.setDefaultField(null);
        assertNull(queryContext.getDefaultField());
    }

    // Test complex scenario with multiple operations
    @Test
    public void test_complexScenario() {
        getMockRequest().setAttribute(Constants.FIELD_LOGS, new HashMap<String, List<String>>());

        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);
