writeQueueNums / readQueueNums

[Attila Wind <at...@swf.technology>]

Hi guys,

I have a question.
When I create a topic apart from the topic name I can also specify 
writeQueueNums / readQueueNums. To me it looks the default is 16-16 for 
these.
but
I can not find what are these queues exactly anywhere in the 
documentation...

Does anyone know what are these?

thanks

When users use orade queues, in order to ensure that the scale operation do
not affect the order of messages, the read and write queues need to be set
separately.

There is only one commit log in rocketmq. Files of consume queues placed in
~/store/consumequeue.
