, to the MediaWiki YouTube channel immediately following the tech talk for you to view at any time. More information about the tech talk: *Hadoop and Beyond. An overview of Analytics infrastructure*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

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

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:

Thanks!
