Databricks and Apache Spark focus on large-scale data processing and analytics using a unified cloud-based platform. Apache Spark is a distributed computing engine that enables fast processing of big data through in-memory computation. Databricks provides a managed environment built on top of Spark that simplifies cluster management, development, and collaboration. This training explains how Spark executes parallel data processing using DataFrames, RDDs, and Spark SQL. It also covers how Databricks enhances Spark with optimized performance, notebooks, and automated scaling. You will learn how to build ETL pipelines, perform data transformations, and run analytics efficiently. The course also highlights best practices for scalable data engineering and cloud-based big data solutions.
