Quotation Exchange view, graph builder

Master: v0.9.2

Front End:

• static html
• websocket
• HighCharts (Doji graph)

Back End:

• ReactPHP (Ratchet for WebSocket)
• ElasticSearch for big data aggregation
• BeanstalkD Queue
• import (bash or php)
• Composer, PSR-4
• Monolog
• ".ENV" environment

@todo

• simple json API
• visual switch for quotation and period
• load real exchange
• performance tests

maybe:

• Ratchet + WAMP + ZMQ
• node.js ws loop
• for too big import stream: split traffic(X % n) for parallel import in different instance with queue controll

Install

#install requirements
sudo apt-get install php7.0 composer beanstalkd postgresql-9.5 php7.0-pgsql php7.0-mbstring

#optional. cur. not ready 
#sudo apt-get install php7.0-dev php-pear
#all questions - ENTER
#sudo pecl install event

wget -qO - https://packages.elastic.co/GPG-KEY-elasticsearch | sudo apt-key add -
echo "deb https://packages.elastic.co/elasticsearch/2.x/debian stable main" | sudo tee -a /etc/apt/sources.list.d/elasticsearch-2.x.list
sudo apt-get update && sudo apt-get install elasticsearch
# not critical but important: configure elasticsearch: name, ip, etc
#sudo nano /etc/elasticsearch/elasticsearch.yml

Using

Daemon for import quotation:

command/daemon/import/quotation_exchange2db.php

Optional: import with AMQP for scaling high traffic

important: direct import is more quickly, if server has free resource important: direct import has minimal guarantee for stable: mem leak elastic can go to repair node with slow insert crush the process leads to a loss of traffic AMQP is depend by high performance, scalable beanstalk (and opensource client)

Required(currently - ): WebSocket

AMQP is require for WebSocket or need implement async elasticsearch client with guzzle or reactphp/http-client or need implement async reactphp/child-process not ready but simple: AMQP+AJAX+API can work without WebSocket

#load daemons can work on other servers with multiple fork
command/daemon/import/quotation_amqp2db.php
command/daemon/import/quotation_amqp2db.php fail

Default exchange IMPORT (not best choice)

#run only one daemons
command/daemon/import/quotation_exchange2amqp.php

Optional exchange IMPORT for hight traffic BASH replacement for quotation_load.php

is direct linux-way socket to amqp pipe for high performance source: https://github.com/src-d/beanstool
