"""
The Mixer 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
operation_mode 3: "Don't look if duplicated content"
- SImply do not bother to check if it is a duplicate
- Simply do not bother to check if it is a duplicate
Note that the hash of the content is defined as the sha1(gzip64encoded).
Every data coming from a named feed can be sent to a pre-processing module before going to the global module.
The mapping can be done via the variable FEED_QUEUE_MAPPING
