Lambda And Kappa

Alex Woodie has a story on two competing data architectures:

Jay Kreps, the co-creator of Apache Kafka and CEO of Confluent, was one of the first big data architects to espouse an alternative to the Lambda architecture, which he did with his 2014 O’Reilly story “Questioning the Lambda Architecture.” While Kreps appreciated some aspects of the Lambda architecture—in particular how it deals with reprocessing data—he stated that the downside was just too great.

“The Lambda architecture says I have to have Hadoop and I have to have Storm and I’m going to implement everything in both places and keep them in sync. “I think that’s extremely hard to do,” Kreps tells Datanami. “I think one of the biggest things hurting stream processing is the amount of complexity that you have to incur to build something. That makes it slow to build applications that way, hard to roll them out, and hard to make them reliable enough to be a key part of the business.

I wonder if we’re seeing the next generation of Kimball v Inmon here, or if one will absolutely dominate.
