What role do Data Engineers play in the implementation of big data solutions?

Data Engineers have an awesome role in the implementation of big data solutions. They need to design and manage scalable architectures capable of handling high volumes of data. They select appropriate technologies that might be Hadoop, Spark, or any form of NoSQL databases in which big data is supposed to reside and be processed. They make sure that the infrastructure supports distributed computing for parallel data processing to support fast querying. They further optimize data pipelines for performance efficiency and reliability to draw insights from large amounts of data within organizations.
