  Top 5 Reasons Not to Use Hadoop for Analytics

As a former diehard fan of Hadoop, I LOVED the fact that you can work on up to Petabytes of data.  I loved the ability to scale to thousands of nodes to process a large computation job.  I loved the ability to store and load data in a very flexible format.  In many ways, I loved Hadoop, until I tried to deploy it for analytics.   That’s when I became disillusioned with Hadoop (it just "ain't all that"). At Quantivo, we’ve explored many ways to deploy H...

Now developers can use the API to get what they want and utilize these data to do what they want to. Developers need to apply for using the API now. Once you get access to this API, then you can search your own real time data and utilize these data as you want to. For ex...

Not all open source projects work this way, but perhaps they should. I stumbled upon this realization while maintaining fog as it grew and grew and grew. Leaving issues open seemed unbearable, but over time the volume far exceeded my ability to keep up. Over time I saw the promise of a better way, but my expectations of open source would need to a...

  C++ for the Real-Time Web

C++? Why on Earth? C++ seems like one of the least likely languages to write a web application in. C++ is associated with complexity, both with language design and the need to manually manage memory. Programming in C++ unleashes a whole class of bugs associated with memory corruption and memory allocation. This is a trade off for giving more power to the developer along generally being much faster than equivalent programs in languages such as Python or Ruby. Real-time Web as a Use Case Making...
