Hadoop and Beyond. An overview of Analytics infrastructure
Channel: MediaWiki
Date: 2014-07-15

In this tech talk we will be presenting the analytics infrastructure that we have recently rolled out in production. By now probably everybody knows that wikimedia hosts an instance of hadoop from which we are going to extract pageview data in the near future. But .. how exactly does the data get there?

We will go over the path that webrequest log data takes from varnish to kafka (a distributed log buffer) to hadoop and the challenges of deploying  this java-based infrastructure in production. We will also talk about how can we query the data with hive, an SQL-like interface. How can you set up this stack on vagrant to play with and, last but not least, how we used hive recently to provide GLAM folks with image view stats: https://commons.wikimedia.org/wiki/Commons:GLAMwiki_Toolset_Project/NARA_analytics_pilot
