At my company, Appuri, we are excited about the possibilities Spark opens up, so we are putting our money where our mouth is. We are co-organizing the Seattle Spark Meetup.
True to the spirit of Spark, this will be a community effort. We are partnering with the formidable Denny Lee from Concur Solutions and Don Watters from eBay, along with the Seattle Big Data community, to arrange a great lineup of speakers. There's strong interest from the community in learning about operationalizing Spark, as well as machine learning.
If you have thoughts on a topic you'd like to see in the meetup series, please email me.
