Understanding Narrow Vs Wide Transformations in Apache Spark under 60 Seconds | FAQ #interview

In Apache Spark, Narrow transformations are preferred whenever possible because they are more efficient and can be executed in parallel without requiring data shuffling. Wide transformations are necessary for operations that require data redistribution or aggregation across partitions, but they incur higher overhead due to data shuffling. Efficient use of narrow transformations can help optimize Spark jobs for better performance and resource utilization.

Most commonly asked interview questions when you are applying for any data based roles such as data analyst, data engineer, data scientist or data manager.
