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

import jakarta.annotation.PostConstruct;

/**
 * Configuration class for query field mappings in the Fess search engine.
 * This class manages field configurations for various query operations including
 * response fields, search fields, facet fields, sort fields, and highlighting.
 * It initializes field mappings from the FessConfig and provides methods to
 * query field properties and capabilities.

        assertEquals(firstInstance.getIndexNumber(), secondInstance.getIndexNumber());
        assertEquals(expectedIndexNumber, secondInstance.getIndexNumber());
    }

    void testMultipleDecodeOperations() throws SMBProtocolDecodingException {
        // First decode
        byte[] buffer1 = new byte[8];

/**

 * merging, reading, and writing.

## 1. Prerequisites

- Install MinIO - [MinIO Quickstart Guide](https://docs.min.io/community/minio-object-store/operations/deployments/baremetal-deploy-minio-on-redhat-linux.html).
- Install `mc` - [mc Quickstart Guide](https://docs.min.io/community/minio-object-store/reference/minio-mc.html#quickstart)

## 2. Enable bucket lifecycle configuration

- Install mc - [MinIO Client Quickstart Guide](https://docs.min.io/community/minio-object-store/reference/minio-mc.html#quickstart)
- Install MinIO - [MinIO Quickstart Guide](https://docs.min.io/community/minio-object-store/operations/deployments/baremetal-deploy-minio-on-redhat-linux.html)
- Configure etcd - [Etcd V3 Quickstart Guide](https://github.com/minio/minio/blob/master/docs/sts/etcd.md)

### 2. Create a new user with canned policy

These credentials can now be used to perform MinIO API operations.

### Using MinIO Console

- Open MinIO URL on the browser, lets say <http://localhost:9000/>
- Click on `Login with SSO`

        throw new IOException("Failed to reconnect durable handle");
    }
}

@Override
public void close() throws IOException {
    try {
        // Normal close operations
        super.close();
    } finally {
        // Don't release durable handle on close if it's persistent
        if (handleManager != null && handleType != HandleType.PERSISTENT) {
