[Sneak Preview] Apache Spark: Preparing for the next wave of Reactive Big Data

Back in summer of 2014, we launched the results of a survey on Java 8, which shared a lot of information we were looking for, but also contained a small golden nugget of data that we didn’t expect: that out of more than 3000 developers surveyed, a shocking 17% of them reported using Apache Spark in production.

So we did another survey with 2100+ respondents drilling down into what developers, data scientists, executives and organizations are looking forward to with Apache Spark. You can download the full version of the report for the whole story, but here is a sneak peak into the findings that we discovered.
