支持全平台编译部署，Linux/Unix/Windows 以及 ARM 平台网关，支持 Docker 镜像制作。

共享订阅(Shared Subscription)

共享订阅(Shared Subscription)支持在多订阅者间采用分组负载平衡方式派发消息:

bash

---------
|       | --Msg1--> Subscriber1
Publisher--Msg1,Msg2,Msg3-->|  EMQ  | --Msg2--> Subscriber2
|       | --Msg3--> Subscriber3
---------

使用方式: 订阅者在主题(Topic)前增加'$queue'或'$share/<group>/'前缀。

本地订阅(Local Subscription)

本地订阅(Local Subscription)只在本节点创建订阅与路由表，不会在集群节点间广播全局路由，非常适合物联网数据采集应用。

使用方式: 订阅者在主题(Topic)前增加'$local/'前缀。

erlang.mk 与 relx

2.0 版本分离 emqttd 主项目和发布项目 emq-relx , 采用 erlang.mk 和 relx 编译发布工具替换 1.x 版本使用的 rebar，项目可以跨平台在 Linux/Unix/Windows 系统下编译。

CoAP 协议支持

2.0 版本支持 CoAP 协议(RFC7252)，支持 CoAP 网关与 MQTT 客户端互通。

CoAP 插件: https://github.com/emqtt/emq_coap

MQTT-SN 协议支持

2.0 版本支持 MQTT-SN 协议，支持 MQTT-SN 网关与 MQTT 客户端互通。

MQTT-SN 插件: https://github.com/emqtt/emq_sn

'K = V'格式配置文件

2.0 版本支持用户友好的'K = V'格式配置文件 etc/emq.conf:

bash

node.name = emqttd@127.0.0.1

...

mqtt.listener.tcp = 1883

...

操作系统环境变量

2.0 版本支持操作系统环境变量。启动时通过环境变量设置 EMQ 节点名称、安全 Cookie 以及 TCP 端口号:

bash

EMQ_NODE_NAME=emqttd@127.0.0.1
EMQ_NODE_COOKIE=emq_dist_cookie
EMQ_MAX_PORTS=65536
EMQ_TCP_PORT=1883
EMQ_SSL_PORT=8883
EMQ_HTTP_PORT=8083
EMQ_HTTPS_PORT=8084

Docker 镜像支持

EMQ-2.0 版本支持 Docker 镜像制作，Dockerfile 开源在: https://github.com/emqtt/emq_docker

Windows 平台支持

2.0 版本完整支持 Windows 平台的编译、发布与运行，支持 Windows 平台下的'emqttd_ctl'控制命令，支持在 Windows 节点间的集群。
