Here’s normal NodeJS function with two parameters – request and response. The incoming requst is automatically parsed for JSON body […]
Scalding is a Scala library. Scalding is easy to work with and reason about the data in distributed systems like Hadoop. It presents the data as a collection and allows to perform the computation on data in a matter that is similar to Scala API, so it appears to the […]
Tableau published a paper on Top 10 Big Data Trends for 2017 that you can find here: http://tabsoft.co/2jXCXar We disagree that speeding up Hadoop as number 1 trend. The author takes the evolutionary approach and not revolutionary one. What needed more and more is the event driven processing. The machinery […]
