September Meetup

Our September meetup is kindly hosted by King.com (http://www.king.com). We'll have the usual drinks and food from 6:30pm onwards, talks will be starting around 7pm.

As this is hosted in their office we need to give names to security, so please make sure to RSVP if you are going to come.

The three talks for the evening are:

• Dr Relational or: How I Learned to Stop Worrying and Love the Database (Andy Done, Data Warehouse Lead, King)

In the face of explosive growth King's Hadoop data warehouse simply wasn't scaling fast enough. Find out why King is extending its Big Data platform with MPP database ExaSol and processing its data 100s of times faster.

• Facebook Scale Graph Processing using Giraph (Nitay Joffe, Software Engineer, Facebook)

This talk will discuss the design and architecture of Giraph - an offline distributed graph processing system built on top of Hadoop. We have scaled Giraph to process very large graphs, at Facebook we run PageRank on a 400 billion edge graph in a matter of minutes. We will dive into the architecture that allows Giraph to scale to very large data sizes.

• GraphChi (Michael Leznik, Head of BI - London, King)

GraphChi, a disk-based system for computing efficiently on graphs with billions of edges. By using a well-known method to break large graphs into small parts, and a novel parallel sliding windows method, GraphChi is able to execute several advanced data mining, graph mining, and machine learning algorithms on very large graphs, using just a single consumer-level computer.
