Google open sources a MapReduce framework for C/C++ by Derrick Harris,
From the post:
Google announced on Wednesday that the company is open sourcing a MapReduce framework that will let users run native C and C++ code in their Hadoop environments. Depending on how much traction MapReduce for C, or MR4C, gets and by whom, it could turn out to be a pretty big deal.
Hadoop is famously, or infamously, written in Java and as such can suffer from performance issues compared with native C++ code. That’s why Google’s original MapReduce system was written in C++, as is the Quantcast File System, that company’s homegrown alternative for the Hadoop Distributed File System. And, as the blog post announcing MR4C notes, “many software companies that deal with large datasets have built proprietary systems to execute native code in MapReduce frameworks.”

Great news but be aware that “performance” is a tricky issue. If “performance” had a single meaning, the TIOBE Index for February 2015 (a rough gauge of programming language popularity) to look quite different over the years.
I remember a conference story where a programmer had written an application using Python, reasoning that resource limitations would compel the client to return for a fuller, enterprise solution. To their chagrin, the customer never exhausted the potential of the first solution. 😉
