About Databricks Apache Spark Certification: 2018-2019

            As you know in Big Data, Data Science & Machine Learning one of the fastest growing platform in the last 5 year is Apache Spark. Reason is simple it is one of the fastest data processing engine among all available. Every BigData solution provider like Cloudera, Hortonworks or MapR had already integrated Spark 2.x framework. Initially if you had worked with Spark 2.x than most of the time you will be working with the RDD (Resilient Data Distributed) which is still core component of Spark, required you write complex programming. However, in Spark 2.x huge improvement is done and new abstract component is developed which is DataFrame or Dataset and you can assume it is as a distributed table with Rows and Columns and working with Spark Framework was made very easy, even if you are not hard core programmer and working as a Data Scientists, Data Analytics then it is a huge relief for you. Major components supported by Spark Frameworks are below.

  • Core Spark & Architecture : Other components of Spark is built on this Core Spark
  • Spark Streaming: Real time and near real time data can be processed.
  • Spark ML: Component provides various machine learning algorithms.
  • Spark SQL: One of most used and optimized component in Spark 2.x. And favored by all the developers.
  • GraphFrames: To process graph related data and applying analytics on this.
  • Programming Languages: One of the best thing if you know any of Java, Scala, Python or R. You can use Spark framework and learning curve will be reduced.

Regarding Certification: Databricks team is founder of Apache Spark and they helped in Development of Apache Spark in every stage. Now they provide their own commercial solution for Apache Spark. Which is used by various organization globally. Hence, Databricks has a very good reputation in the Industry. At the same time getting certified for Apache Spark from Databricks has a lot of benefits. Also this is the only certification which is available on the Spark 2.x version with Open Source Apache Spark. So it is highly recommended if you are going for Spark Certification then go for this one.

Who should attend this certification?

In this decade you have seen most popular or trending technologies for the professionals working on the data are BigData Engineer, Data Scientist, Data Analytics engineer, Machine Learning, BigData Programmer. If you are working or plan to work on the above domain then you are choosing one of the high paying fields for this decade at-least. It is no more hype, its reality. You can check any job portal and to check the current openings. So we recommend this certification should be added in your resume if you are already working or transitioning or planning to work in above domain

  • If you are a developer : go for it
  • If you are a data analytics engineer: It opens a door to become data scientists.
  • If you are already working as a Data scientist: Go for this certification, one of the fastest growing technology for data scientist.

We don’t recommend this certification for the professionals who are working in the following domain. Until they wanr to transition their career.

  • Database Administrator

It is very difficult to write individual names who is using even there is a huge list of companies from where the professionals are using this material like Big Consultancies and many product based companies are using it. We can tell few names like TCS, Infosys, Accenture, IBM, Oracle, and Capgemini and there are many startups and Investment Bank employees are using Spark technology.

I already have good knowledge of Apache Spark, why should I do Certification?

If you are serious about your career growth than just having a knowledge is not enough. You should try every possible way to grow your career. We have seen many professionals are having good working knowledge of the technology. But they cannot communicate correctly and their growth speed is much slower. A person who can show (In technology world you need both show of as well as knowledge) its skills all possible ways can reach on top, much faster than a person who is having the knowledge but cannot show. So becoming a certified professional will add one more dimension in your career growth. We recommend go for the certification to prove your skill and grow faster in your career. If certification would have not value then companies would not spending so much money on that. It is highly recommended for the professional who already know the Spark then get certified. It make a huge difference. Even on various job portal you can check they are looking for certified professionals only.
