What is a Big Data Engineer?
Before you learn what is a Big Data Engineer, it is important to understand what is Big Data. In the 2000s there was minimal data available to companies and governments, but it all changed when the internet became available for household use and social media platforms like Instagram, Facebook, and others emerged.
This led to a sudden and significant increase in the data available to companies. Now, so much data is available that it becomes difficult to understand and derive something meaningful from it. This is known as Big Data.
Companies need professionals who possess the skills to manage such data and make useful observations that can help make better decisions.
Such professionals are known as Big Data Engineers and handle different types of Big Data such as Excel & SQL tables, Email and XML files, and images and videos. They work with tools and frameworks such as Hadoop, Spark, Cassandra, and others to manage, handle, analyze, & interpret the data.
Thus, a Big Data Engineer is a data specialist who designs, builds, tests, and maintains complex data processing systems compatible to work with large data sets. They also collect, clean, transform, and enrich data so that better decisions can be made.
