Why is Spark RDD immutable?

Question Posted / sai_dasari


Why is Spark RDD immutable?..

Answer / Ayus Shankhdhar

Spark RDDs are immutable to ensure fault-tolerance, data consistency, and ease of parallel computation. An immutable RDD ensures that once a dataset is created, it cannot be modified; instead, new RDDs can be generated based on existing ones using various transformations.
