Tutorial: Designing a GraphQL API

This tutorial was created by Shopify for internal purposes. We've created a public version of it since we think it's useful to anyone creating a GraphQL API.

It's based on lessons learned from creating and evolving production schemas at Shopify over almost 3 years. The tutorial has evolved and will continue to change in the future so nothing is set in stone.

Magento Enterprise 1.12 cluster

Scaling Magento presentation with 60 slides and notes, which was then reviewed by Alan Storm.

I've had the opertunity to try a variety of different server configurations but never really got around to trying HHVM with Magento until recently. I thought I would share a detailed walkthrough of configuring a single instance Magento server running Nginx + Fast CGI + HHVM / PHP-FPM + Redis + Percona. For the purpose of this blog post I'm assuming you are using Fedora, CentOS, or in my case RHEL 6.5.

Please note: I'm 100% open to suggestions. If you see something I did that needs to be done a different way, please let me know. I haven't included my Perconca my.conf file yet. I will shortly. Also I plan on trying this same test with HHVM 3.3 and PHP 7.

	Why is there no such DataImportHandler thing in ElasticSearch? Uhm, well ... but because:

	1. You should really consider your own scripts
	(be it jvm based, perl, ruby, php, nodejs/javascript)
	to feed ElasticSearch via bulk indexing:
	http://www.elasticsearch.org/guide/reference/java-api/bulk.html

	2. There are two projects doing it already:
	* http://code.google.com/p/sql-to-nosql-importer/
	* https://github.com/Aconex/scrutineer (keeps DB in synch with ES or solr!)
