Have you heard about Spark (http://spark.incubator.apache.org/) already? In essence: take Hadoop, remove Map-Reduce requirement, add in-memory processing, provide very nice API (interactive!) and make it up to 100x faster.
Przemek Maciolek will give an introduction to Spark and related technologies, together with some real live examples.
Talks - Lightning or not
Feeling like would like to share some experiences with Big Data? You're most welcome to!
If possible, contact with the organisers in advance, so we can have a nice list of planned talks (and send update before the meetup). However, if an Eureka moment comes to you at the very last minute - it's fine to just bring ideas and share them with the rest of us.
There's a Big Data conference on March 27th in London, with free admission (though the number of places is limited): http://www.computingsummit.com/bigdata If anyone is interested, please contact [masked]
