The ZMQ_Feed_Q Module
|
|
=====================
|
|
|
|
This module is consuming the Redis-list created by the ZMQ_Feed_Q Module,
|
|
And save the paste on disk to allow others modules to work on them.
|
|
|
|
..todo:: Be able to choose to delete or not the saved paste after processing.
|
|
..todo:: Store the empty paste (unprocessed) somewhere 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.
|
|
*Need the ZMQ_Feed_Q Module running to be able to work properly.
