Re: [mosquitto-dev] A non-centralize Mosquitto cluster design.
Hi Jianhui,

Thank you for the further information, but I'm not sure the cluster can expand the performance.
The amount of '2000 PUB/SUBs' seems too small, it can be handled by using only one broker.
Could you simples the scenarios, and  show the performance change in according with the number of brokers?

Regards,
Tatsuzo

Hi Osawa,


I have continuously write and debug the non-centralized cluster, and test it with a light load, about 2000 SUB/PUB pair, fortunately it work as expected, without errors. Attached is the test report. More stress is needed in future testing.


These days I've also thought of some other business MQTT cluster, almost Erlang or Java based, which contains too much nodes/services such as broker, event dispatcher, subscription in-memory cache, persistence database, distributed coordinator, etc., with high latency(400ms~500ms), and depend on the availability of each key service.

In some ways, I think Mosquitto should take it's role as Redis in NoSQLs, ZeroMQ in Message Queues, make the very very low latency as it's most significant advantage..

Your e-mail software made the subjects include multi-byte characters.

Eclipse is probably best known as a Java IDE, but it is more: it is an IDE framework, a tools framework, an open source project, a community, an eco-system, and a ...



Could you correct the subjects from the next post?
