Release Name: West of West Lake

The EMQ Version 2.0, named "West of West Lake", has been released with a lot of improvements and enhancements, and is ready to deploy in production now.

  1. First of all, the EMQ broker now supports Shared Subscription and Local Subscription.
  2. Supports CoAP(RFC 7252) and MQTT-SN protocol/gateway.
  3. Adopt a more user-friendly k = v syntax for the new configuration file.
  4. Add more hooks and new plugins, integrate with HTTP, LDAP, Redis, MySQL, PostgreSQL and MongoDB.
  5. Cross-platform Builds and Deployment. Run the broker on Linux, Unix, Windows, Raspberry Pi and ARM platform.

Shared Subscription

Shared Subscription supports Load balancing to distribute MQTT messages between multiple subscribers in the same group:


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

Create a shared subscription with $queue/ or $share/<group>/ prefix:

Prefix Examples
$queue/ mosquitto_sub -t '$queue/topic
$share// mosquitto_sub -t '$share/group/topic

Local Subscription

The Local Subscription will not create global routes on clustered nodes, and only dispatch MQTT messages on local node.

Usage: subscribe a topic with $local/ prefix.

erlang.mk and relx

The EMQ 2.0 adopts erlang.mk_ and relx_ tools to build the whole projects on Linux, Unix and Windows.

CoAP Support

The EMQ 2.0 supports CoAP(RFC7252) protocol/gateway now, and supports communication between CoAP, MQTT-SN and MQTT clients.

CoAP Protocol Plugin: https://github.com/emqtt/emqttd_coap

MQTT-SN Support

The EMQ 2.0 now supports MQTT-SN protocol/gateway.

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

New Configuration File

The release integrated with cuttlefish library, and adopted a more user-friendly k = v syntax for the new configuration file:

    ## Node name
    node.name = emqttd@127.0.0.1
    ...
    ## Max ClientId Length Allowed.
    mqtt.max_clientid_len = 1024
    ...
