Data storage and processing have been leaps and bounds in the last two decades. Whether finance, manufacturing, or any other business, industries continuously generate a large quantity of data. They have realized that data is one of their valuable assets and can be used to bring positive outcomes to their businesses. This is because if you process and analyze a massive amount of data correctly, it will show wonders for you. That's why industries focus on data processing and analyzing to retrieve valuable insights and information
Undoubtedly, the pace of generating data is very high in many businesses, mainly social media companies such as Twitter, Facebook, etc. As a result, they constantly accumulate a large quantity of data daily. Know that it is not an easy deal to manage this big data and retrieve helpful information from the data. You need to effectively process the raw data to make it ready for analysis before retrieving helpful information from the data. Only qualified professionals can process the raw big data by applying suitable techniques.
Now, the role of big data engineers comes into the picture. Essentially, big data engineers transform raw data into well-organized and valuable data and help businesses to reap plenty of benefits from big data. There is a huge demand for big data engineers nowadays all over the world. That’s why a career in big data is considered one of the fast-growing and highly-paid careers.
On that note, this blog is prepared for aspirants who wish to become big data engineers. This blog is a quick guide that unpacks the concept of big data, data engineering, and the skills needed to become a big data engineer.
Here we go!

Big data is not only a large quantity of data but an ever-growing entity. No surprise that according to the recent survey of Statista, the volume of data generated worldwide is 79 zettabytes up to the year 2021. It is expected that it will reach 181 zettabytes by 2025.
Big data consists of data collected from many sources in different formats. Three types of data are structured, unstructured, and semi-structured. The data can be customer data, transactions, operational data, or others. Credit card data, e-commerce, POS transactions, social media, and sensor reading of IoT devices are a few examples of data. This data would usually be in petabytes and terabytes. Big data engineers use many tools to process this raw data into organized and actionable data. In this regard, they use tools such as Hadoop, Cassandra, Spark, Apache Storm, etc.

It is one of the engineering domains that deal with collecting, processing, storing, and organizing big data effectively. Not just that, it also includes developing systems for processing big data. When it comes to storage, big data storage is entirely different from standard data storage. For instance, if you want to store big data, you need to use a dynamic schema in databases – not a fixed schema. Another thing is that you have to use distributed databases for storing big data – not centralized databases.
Scaling is yet another crucial thing in managing big data because it needs dynamic storage systems to keep pace with the ever-increasing data volume. Cloud storage offers the best solution to meet dynamic scaling requirements.
Okay! What does actually a big data engineer mean? Let’s find the answer in this section. A typical big data engineer builds, verifies, and maintains data processing systems. They usually have many crucial roles and responsibilities in managing big data and data processing systems. Here, we will list them all one by one.
As mentioned earlier, a big data engineer transforms the raw data into organized data. Do you want to know how they perform this? Read ahead to know the answer.
Essentially, a big data engineer performs the ETL process. It means that they extract data from multiple sources, transform the raw data into the quality and actionable data using data processing systems, and finally load the data in warehouses and data lakes where it will be in the ready state for downstream processing.
Let’s see how a big data engineer does this in the following step-by-step.
At first, a big data engineer builds and maintains a big data environment. This is where they build large-scale data processing systems and other related resources. This environment includes the required data architecture and tools to process big data. Generally, the data architecture is built based on business needs. Big data engineers build robust processing systems for data ingestion as well as data processing.
At this stage, big data engineers convert the collected raw data into organized, high-quality, and actionable data. It allows them to apply data transformation methods or algorithms to retrieve valuable information from the data. After that, they store data in data warehouses and data lakes for downstream processing. It is important to note that the transformed data will undoubtedly satisfy the quality and compliance standards for further analysis.
Next, big data engineers collaborate with data scientists and analysts to improve the quality of transformed data using different algorithms and advanced tools. They use their expertise by integrating different programming languages and tools to create the best data processing models. As a result, they build efficient data processing models and support to produce high-quality and organized data.
