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

        int start = 0;

        // Write server name (16 bytes, null padded)
        byte[] nameBytes = serverName.getBytes(StandardCharsets.US_ASCII);
        System.arraycopy(nameBytes, 0, buffer, bufferIndex, Math.min(nameBytes.length, 15));
        bufferIndex += 16;

        // Write version major (1 byte)
        buffer[bufferIndex++] = (byte) versionMajor;

        // Write version minor (1 byte)

    if (required == from) {
      int min = from;
      for (int index = from + 1; index <= to; index++) {
        if (array[min] > array[index]) {
          min = index;
        }
      }
      if (min != from) {
        swap(array, min, from);
      }
      return;
    }

constraints.Max.message = {item} は {value} 以下にしてください。
constraints.Min.message = {item} は {value} 以上にしてください。
constraints.NotNull.message = {item} は未入力です。
constraints.Null.message = {item} は null でなければなりません。
constraints.Past.message = {item} は過去の値にする必要があります。
constraints.Pattern.message = {item} が 「{regexp}」 に一致しません。
constraints.Size.message = {item}のサイズは {min} 文字から {max} 文字の範囲にしてください。

            String reqPath = "\\\\server\\share\\path\\file";
            // Ensure consumed is within bounds to avoid StringIndexOutOfBoundsException
            consumed = Math.min(consumed, reqPath.length());

            referralData = DfsReferralDataImpl.fromReferral(mockReferral, reqPath, System.currentTimeMillis() + 10000, consumed);
        }
    }
