|
The ZMQ_PubSub_Lines Module
|
|
============================
|
|
|
|
This module is consuming the Redis-list created by the ZMQ_PubSub_Line_Q Module.
|
|
|
|
It perform a sorting on the line's length and publish/forward them to differents
|
|
channels:
|
|
|
|
*Channel 1 if max length(line) < max
|
|
*Channel 2 if max length(line) > max
|
|
|
|
The collected informations about the processed pastes
|
|
(number of lines and maximum length line) are stored in Redis.
|
|
|
|
..note:: Module ZMQ_Something_Q and ZMQ_Something are closely bound, always put
|
|
the same Subscriber name in both of them.
|
|
|
|
Requirements
|
|
------------
|
|
|
|
*Need running Redis instances. (LevelDB & Redis)
|
|
*Need the ZMQ_PubSub_Line_Q Module running to be able to work properly.
