DataStax Survey Shows NoSQL Skills Gap, Demand for Apache Cassandra

Indeed, according to the DataStax survey, Apache Cassandra is becoming even more important for engineers to understand and be able to use. Nearly three-quarters (73 percent) of survey respondents said Apache Cassandra is critical to their job function. Of this group, nearly 60 percent said Apache Cassandra was not critical to their job six months ago. Yet, only eight percent of respondents said they think the current pool of skilled NoSQL workers is enough for the demand in the database industry.

The survey also showed that there is a high demand for more Apache Cassandra and NoSQL training courses, as 37 percent of the survey respondents said they are interested in increasing their knowledge of Apache Cassandra, specifically for personal growth reasons. And 85 percent of the survey respondents said free courses are one of the most important factors to encourage participation in a new training course, followed by an online format and the ability to proceed through a course at his or her own pace.

The DataStax survey also showed some interesting movement in terms of female developers Hasker said. He noted that while there has been a focus on the paucity of female developers, when it comes to Apache Cassandra and DataStax the breakdown is about 90 percent male and 10 percent female, “which while absolutely is nothing to be proud of, is about double the industry average, which is about 5 percent for female developers and 95 percent male,” Hasker said.

However, in some of the emerging regions they have a younger demographic and a more even ratio of male to female developers, he added.

“I think the age demographic is key in this,” Hasker said. “When we look at the population of female developers they tend to be in the 25 to 35 year-old range. And that’s a little younger than the typical male developer in the survey. So I think recently, over the past two to three years, if you’re a female developer and you’re young in the field, you do not want to pick up an old technology like an Oracle database. You want to be part of the new wave. And as you go to a younger demographic we become even more popular there. I think that’s what’s at play here, which bodes great for the future.”

Meanwhile, a quarter of the DataStax survey respondents said they held existing certifications in Hadoop, MongoDB, SQL Server and Oracle, but felt it was necessary to receive additional training and certification in Apache Cassandra. DataStax, in conjunction with O’Reilly Media, offers a certification program for Cassandra to turn out certified Cassandra developers, administrators and architects. They certified just under 1,000 developers last year, Hasker said.

According to the Gartner report, Bridging the Strategy Gap for Big Data Adoption, “Skills shortages remain a challenge and searches for ‘qualified data scientists’ have become project impediments. Many organizations said that service providers didn't have the industry depth and related business process skills. In many cases, the skills were outside an organization's region, and the organization found it difficult to transfer them to its operations. Some of these organizations decided to ‘go it alone’ and then discovered that they faced multiple challenges in addition to a steep learning curve.”
