"""
The ZMQ_Feed_Q Module
=====================
This module is consuming the Redis-list created by the ZMQ_Feed_Q Module.
This module take all the feeds provided in the config.
Depending on the configuration, this module will process the feed as follow:
operation_mode 1: "Avoid any duplicate from any sources"
- The module maintain a list of content for each paste
- If the content is new, process it
- Else, do not process it but keep track for statistics on duplicate
operation_mode 2: "Keep duplicate coming from different sources"
- The module maintain a list of name given to the paste by the feeder
- If the name has not yet been seen, process it
- Elseif, the saved content associated with the paste is not the same, process it
- Else, do not process it but keep track for statistics on duplicate
Note that the hash of the content is defined as the gzip64encoded
Requirements
------------
*Need running Redis instances.
*Need the ZMQ_Feed_Q Module running to be able to work properly.
