What is RDD? Comprehensive Guide to RDD with Advantages

WebJul 23, 2024 · Resilient Distributed Datasets (RDDs) are designed to be immutable. One of the reasons behind making them immutable lies in fault tolerance and avoidance as they are handled by many processes and possibly many nodes at the same time. This can avoid race conditions and also avoid the overhead involved in trying to control those conditions. Web0 votes. There are few reasons for keeping RDD immutable as follows: 1- Immutable data can be shared easily. 2- It can be created at any point of time. 3- Immutable data can easily live on memory as on disk.
