The ZMQ_Sub_Indexer_Q Module
|
|
============================
|
|
|
|
The ZMQ_Sub_Indexer_Q module subscribes to PubSub_Global ZMQ channel
|
|
and bufferizes the data in a Redis FIFO.
|
|
|
|
The FIFO will be then processed by the Indexer scripts (ZMQ_Sub_Indexer)
|
|
handling the indexing process of the files seen.
