[![Build Status](https://travis-ci.org/binary-com/perl-Mojo-Redis-Processor.svg?branch=master)](https://travis-ci.org/binary-com/perl-Mojo-Redis-Processor) [![Coverage Status](https://coveralls.io/repos/github/binary-com/perl-Mojo-Redis-Processor/badge.svg?branch=master)](https://coveralls.io/github/binary-com/perl-Mojo-Redis-Processor?branch=master) # perl-Mojo-Redis-Processor # NAME Mojo::Redis::PubSub - Message distribution and processing using Redis backend. # DESCRIPTION This module will encapsulate a communication process between Websocket code implemented as a Mojo app which need stream of prices and daemons which get the pricing parameters and publish market price whenever there is a market signal (trigger). As price that be common between different Mojo children they will race over setting a pricing request in Redis. It will be handles by SET NX in Redis. Daemon will take the pricing jobs for every Market signal calculate and publish the price back for Mojo children using Redis PUB/SUB. # VERSION 0.02 # SYNOPSIS Mojo app which wants to send data and get stream of processed results will look like: use Mojo::Redis::Processor; use Mojolicious::Lite; my $rp = Mojo::Redis::Processor->new({ data => 'Data', trigger => 'R_25', }); $rp->send(); my $redis_channel = $rp->on_processed( sub { my ($message, $channel) = @_; print "Got a new result [$message]\n"; }); app->start; Try it like: $ perl -Ilib ws.pl daemon Processor daemon code will look like: use Mojo::Redis::Processor; use Parallel::ForkManager; use constant MAX_WORKERS => 1; $pm = new Parallel::ForkManager(MAX_WORKERS); while (1) { my $pid = $pm->start and next; my $rp = Mojo::Redis::Processor->new; $next = $rp->next(); if ($next) { print "next job started [$next].\n"; $rp->on_trigger( sub { my $payload = shift; print "processing payload\n"; return rand(100); }); print "Job done, exiting the child!\n"; } else { print "no job found\n"; sleep 1; } $pm->finish; } Try it like: $ perl -Ilib daemon.pl Daemon needs to pick a forking method and also handle ide processes and timeouts. # SOURCE CODE [GitHub](https://github.com/binary-com/perl-Mojo-Redis-Processor) # AUTHOR binary.com, `` # BUGS Please report any bugs or feature requests to [https://github.com/binary-com/perl-Mojo-Redis-Processor/issues](https://github.com/binary-com/perl-Mojo-Redis-Processor/issues). # LICENSE AND COPYRIGHT Copyright (C) 2016 binary.com This program is free software; you can redistribute it and/or modify it under the terms of the the Artistic License (2.0).
