Facebook's Corona: When Hadoop MapReduce Wasn't Enough 42

Nerval's Lobster writes "Facebook's engineers face a considerable challenge when it comes to managing the tidal wave of data flowing through the company's infrastructure. Its data warehouse, which handles over half a petabyte of information each day, has expanded some 2500x in the past four years — and that growth isn't going to end anytime soon. Until early 2011, those engineers relied on a MapReduce implementation from Apache Hadoop as the foundation of Facebook's data infrastructure. Still, despite Hadoop MapReduce's ability to handle large datasets, Facebook's scheduling framework (in which a large number of task trackers that handle duties assigned by a job tracker) began to reach its limits. So Facebook's engineers went to the whiteboard and designed a new scheduling framework named Corona." Facebook is continuing development on Corona, but they've also open-sourced the version they currently use.

    Too bad that's 99.9% junk I don't care about.

    But between you and 1000 other people who care about slightly different sets, much of it is stuff that someone cares about.

    This. 99.9% (at least) of the entire internet is junk that any one person doesn't care about. But every bit has someone who cares about it (or did at one time) or it wouldn't be there.

    Well. I opened the story expected some reflexive Facebook-bashing, and I wasn't disappointed. When are people going to realize that FB's just another internet company with a reasonably successful business model, and worthy of neither adulation nor hatred?

Whom computers would destroy, they must first drive mad.
