Apache Spark with Python, Returns a new RDD by applying the function on each data element, Returns a new dataset formed by selecting those elements of the source on which the function returns true, Returns an RDD with elements in the specified range, upper to lower, Similar to the map function but returns a sequence, instead of a value, Aggregates the values of a key using a function, Similar to map but runs separately on each partition of an RDD, Similar to the map partition but also provides the function with an integer value representing the index of the partition, Samples a fraction of data using the given random number generating seeds, Returns a new RDD containing all elements and arguments of the source RDD, Returns a new RDD that contains an intersection of elements in the datasets, Returns the Cartesian product of all pairs of elements, Returns a new RDD created by removing the elements from the source RDD with common arguments, Joins two elements of the dataset with common arguments; when invoked on (A,B) and (A,C), it creates a new RDD, (A,(B,C)), Gets the number of data elements in an RDD, Gets all data elements of an RDD as an array, Aggregates data elements into an RDD by taking two arguments and returning one, Executes the function for each data element of an RDD, Retrieves the first data element of an RDD, Writes the content of an RDD to a text file, or a set of text files, in the local system, Avoids unnecessary recomputation; it is similar to persist(MEMORY_ONLY), Persists an RDD with the default storage level, Marks an RDD as non-persistent and removes the block from memory and disk, Saves a file inside the checkpoint directory and removes all the references of its parent RDD, Stores an RDD in an available cluster memory as a deserialized Java object, Stores an RDD as a deserialized Java object; if the RDD does not fit in the cluster memory, it stores the partitions on the disk and reads them, Stores an RDD as a serialized Java object; it is more CPU intensive, Similar to the above but stores in a disk when the memory is not sufficient, Similar to other levels, except that partitions are replicated on two slave nodes.
