Ville Tuulos
Erlang hacker at Nokia Research and initiator of the Disco Project

Ville Tuulos is a researcher with Nokia Research in Palo Alto. He has been working with large data sets since 1999, building solutions for statistical information retrieval. After several misguided attempts to orchestrate highly distributed systems in C and Python, he found Erlang in 2006. He is also co-author of the book "Mobile Python - Rapid application development on the mobile platform". In 2007 he started to build Disco, an Erlang / Python implementation of the Map/Reduce framework for distributed computing. Disco is now used by Nokia and others for quick prototyping of data-intensive software, using hundreds of gigabytes of real-world data.

Sponsored Talk: How Nokia uses Disco to mine terabytes of logs daily

Disco is an open-source MapReduce framework whose core is written in Erlang. Today, Disco is used by Nokia to store and process tens of terabytes of constantly updating log data.

We will talk about tricky issues we have faced when running Disco with production data, such as heterogeneous workloads, multiple concurrent users, and evolving schemas. Thanks to this evolutionary pressure, Disco is starting to support exciting new features, such as jobs written in arbitrary programming languages as first-class citizens.

Target audience: Anyone interested in Big Data and MapReduce, in particular developers of data-intensive Erlang applications.
