Description: In the context of data processing frameworks like Apache Spark, ‘Row-wise’ refers to operations performed on each row of a DataFrame or RDD (Resilient Distributed Dataset). These operations allow for efficient manipulation and transformation of data, leveraging the parallel processing capabilities of the framework. When working with large volumes of data, it is essential to apply functions to each row effectively, which is achieved through methods like ‘map’, ‘filter’, and ‘foreach’. These functions enable developers to perform calculations, filtering, and specific transformations on each record, facilitating data analysis and preparation for subsequent tasks such as machine learning or visualization. The flexibility of row-wise operations in distributed data processing environments is one of the features that distinguishes them from other data processing tools, as it allows users to customize their analyses and optimize performance across various platforms.
