Talks scheduled thus far:

Speaker: Alexander Lorenz

After a serious time of running in large installation the flume team
decided to rewrite flume completely. In this session Alex will show you
the new stack, what we changed and why. FlumeNG is a apache incubation
project and licensed to Apache License v2.

Alex is an hadoop / noSQL Engineer working within Cloudera's Customer
Operations Engineering team. Within the hadoop eco system, Alex
specializes in sqoop and flume. He also has worked, since the late 80's,
on various open source projects including Linux. He blogs - and
sometimes gives presentations - from Germany to evangelize Hadoop.

Speaker: Sebastian Schelter

Introducing Apache Giraph for Large Scale Graph Processing

Web and online social graphs have been rapidly growing in size and scale
during the past decade. Processing such graphs which consist of millions
of vertices and hundreds of millions to billions of edges is a huge
technical challenge. Experience shows that the Map/Reduce paradigm is no
good fit for working with large graph structures. This talk will give an
introduction to Apache Giraph, a system that implements the
bulk-synchronous parallel (BSP) model in a way that is extremely well
suited for implementing graph algorithms. Giraph is a very young project
which is currently developed by people working at leading internet
platforms such as Facebook, Twitter, LinkedIn and can be run on a
standard Hadoop infrastructure.

Sebastian Schelter is a PhD student from the Database Systems and
Information Management Group (DIMA) of TU Berlin. He is also committer
and PMC member of Apache Mahout and Apache Giraph.
