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 item
|
|
- If the content is new, process it
|
|
- Else, do not process it but keep track for statistics on duplicate
|
|
|
|
DISABLED
|
|
operation_mode 2: "Keep duplicate coming from different sources"
|
|
- The module maintain a list of name given to the item by the feeder
|
|
- If the name has not yet been seen, process it
|
|
- Elseif, the saved content associated with the item 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).
