+# MQTT Protocol
+
+## 1. Overview
+
+MQTT (Message Queuing Telemetry Transport) is a lightweight messaging protocol designed for IoT and low-bandwidth environments. It operates on a Publish/Subscribe (Pub/Sub) model, enabling efficient and reliable bidirectional communication between devices. Its core objectives are low power consumption, minimal bandwidth usage, and high real-time performance, making it ideal for unstable networks or resource-constrained scenarios (e.g., sensors, mobile devices).
+
+IoTDB provides deep integration with the MQTT protocol, fully compliant with MQTT v3.1 (OASIS International Standard). The IoTDB server includes a built-in high-performance MQTT Broker module, eliminating the need for third-party middleware. Devices can directly write time-series data into the IoTDB storage engine via MQTT messages.
+

+
+
+## 2. Configuration
+
+By default, the IoTDB MQTT service loads configurations from `${IOTDB_HOME}/${IOTDB_CONF}/iotdb-system.properties`.

+# MQTT 协议
+
+## 1. 概述
+
+MQTT 是一种专为物联网（IoT）和低带宽环境设计的轻量级消息传输协议，基于发布/订阅（Pub/Sub）模型，支持设备间高效、可靠的双向通信。其核心目标是低功耗、低带宽消耗和高实时性，尤其适合网络不稳定或资源受限的场景（如传感器、移动设备）。
+
+IoTDB 深度集成了 MQTT 协议能力，完整兼容 MQTT v3.1（OASIS 国际标准协议）。IoTDB 服务器内置高性能 MQTT Broker 服务模块，无需第三方中间件，支持设备通过 MQTT 报文将时序数据直接写入 IoTDB 存储引擎。
+
+![](/img/mqtt-table-1.png)
+
+## 2. 配置方式
+
+默认情况下，IoTDB MQTT 服务通过`${IOTDB_HOME}/${IOTDB_CONF}/iotdb-system.properties`加载配置。
+
+具体配置项如下：

+# MQTT 协议
+
+## 1. 概述
+
+MQTT 是一种专为物联网（IoT）和低带宽环境设计的轻量级消息传输协议，基于发布/订阅（Pub/Sub）模型，支持设备间高效、可靠的双向通信。其核心目标是低功耗、低带宽消耗和高实时性，尤其适合网络不稳定或资源受限的场景（如传感器、移动设备）。
+
+IoTDB 深度集成了 MQTT 协议能力，完整兼容 MQTT v3.1（OASIS 国际标准协议）。IoTDB 服务器内置高性能 MQTT Broker 服务模块，无需第三方中间件，支持设备通过 MQTT 报文将时序数据直接写入 IoTDB 存储引擎。

+
+## 2. 配置方式
+
+默认情况下，IoTDB MQTT 服务通过`${IOTDB_HOME}/${IOTDB_CONF}/iotdb-system.properties`加载配置。
+
+具体配置项如下：
+
