Welcome, developers!
It's good to have options. Whether you're choosing a cola, a car, or a credit card, it helps to have healthy competition
in the marketplace. And if data analytics is your game, you benefit from a range of alternatives to the most well-known
option, Hadoop. This week's top feature, "Spark,
an alternative for fast data analytics," takes a look at one such alternative. Spark is a scalable data analytics
platform that incorporates primitives for in-memory computing, so it offers performance advantages over Hadoop's cluster
storage approach. Spark is implemented in and exploits the Scala language, making Spark an efficient means of processing
distributed data sets. Spark and Scala are still under development, but it's already clear that they are poised to give
Hadoop a run for its money.
The only downside to all this competition? It takes me 15 minutes to choose a shampoo.
Until next week,
John Swanson and the developerWorks editorial team
