Inductive Bias

Apache Hadoop receives lots of attention from large US corporations who are using the project to scale their data processing pipelines:

“Facebook uses Hadoop and Hive extensively to process large data sets. [...]” (Ashish Thusoo, Engineering Manager at Facebook), "Hadoop is a key ingredient in allowing LinkedIn to build many of our most computationally difficult features [...]" (Jay Kreps, Principal Engineer, LinkedIn), "Hadoop enables [Twitter] to store, process, and derive insights from our data in ways that wouldn't otherwise be possible. [...]" (Kevin Weil, Analytics Lead, Twitter). Found on Yahoo developer blog.

However the system's use is not limited to large corporations only: With 101tec, Zanox, nugg.ad, nurago also local German players are using the project to enable new applications. Add components like Lucene, Redis, CouchDB, HBase and UIMA to the mix and you end up with a set of majour open source components that allow developers to rapidly develop systems that until a few years ago were possible only either in Google-like companies or in research.

The Berlin Apache Hadoop Get Together started in 2008 allowed to learn more on how the average local company leveraged this software. It is a platform to get in touch informally, exchange knowledge and best practices across corporate boundaries.

After three years of organising that event it is time to hand it over to new caring hands: David Obermann from Idealo kindly volunteered to take over organisation. He is a long-term attendee of the event and will continue it in the roughly the same spirit as before: Technical talks on success stories by users, new features by developers - not solely restricted to Hadoop only but also taking into account related projects.

A huge Thank You for taking up the work of co-ordinating, finding a venue and a sponsor for the videos goes to David! If any of you attending the event think that you have an interesting story to share, would like to support the event financially or just help out please get in touch with David.

Looking forward to the next Apache Hadoop Get Together Berlin. Watch this space for updates on when and where it will take place.

This is to announce the next Apache Hadoop Get Together sponsored by Cloudera and Zanox that will take place in the Zanox Event Campus in Berlin.

When: January 27th 2011, 6p.m.

Where: zanox Event Campus (Please mark the changed event location.)

As always there will be slots of 30min each for talks on your Hadoop topic. After each talk there will be a lot time to discuss. We head over to a bar after the event for some beer and something to eat.

Talks scheduled so far:

Simon Willnauer: "Lucene 4 - Revisiting problems for speed"

Abstract: This talk presents a brief case study of long standing problems in Lucene and how they have been approached to gain sizable performance improvements. Each of the presented problems will have brief introduction, implemented solution and resulting performance improvements. This talk might be interesting even for non-lucene folks.

Josh Devins: "Title: Hadoop at Nokia"
Abstract: In this talk, Josh will outline some of the ways in which Nokia is using Hadoop. We will start by having a quick look at the practical side of getting started with Hadoop and outline cluster hardware and configuration and management with tools like Puppet. Next we'll dive head first into how Hadoop and its' ecosystem are being utilized on a daily basis to perform business analytics, drive machine learning and help build data-driven products. We will also touch on how we go about collecting metrics from dozens of applications distributed in multiple data centers around the world. An open Q&A session will follow.

Paolo Negri: "The order of magnitude challenge: from 100K daily users to 1M "
Abstract: "Social games backends share many aspects of normal web applications, but exasperate scaling problems, follow this talk to see how we evolved and brought a plain ruby on rails app to sustain 5000 reqs/sec, moved part of our data from sql to nosql to reach 5 millions queries per minute and see what we learned from this experience."

Please do indicate on Upcoming or Xing if you are coming so we can more safely plan capacities.

A big Thank You goes to zanox for providing the venue for free for our event as well as to Cloudera for supporting videos being taped of the presentations.

Looking forward to seeing you in Berlin,
Isabel
