Pyspark Transformation and Actions RDD Transformation Examples Some of the examples of RDD transformations are: flatmap() map() reduceByKey() filter() sortByKey() RDD Actions Example some of the examples of RDD actions are: count() first() max() reduce() take() collect() lets us understand by code how RDD is fault tolerant, immutable, how lazy evaluation works and also understand its distributed nature. lets define a RDD , while converting a data to RDD, it is not directly loaded in memory, first of all a lineage graph is made for the data, such that even if any node crashes in future, data can be recreated. This lineage graph helps in fault tolerance by allowing Spark to recreate lost data partitions in case of any reason causing node failure. RDDs are distributed across multiple nodes in a cluster, allowing parallel processing of data records. rdd = sc.parallelize([ 1 , 2 , 3 , 4 , 5 ]) the immutability nature of RDD can be understand such that, notice now we didnt changed...
