tolerance than other tools?Existing data flow systems are less efficient at processing two applications: iterative algorithms, which are common in graph applications and machine learning fields, and interactive data mining tools. In both cases, storing the data in memory can greatly improve performance. To effectively implement fault tolerance, the RDD provides a highly restricted shared memory that the RDD is read-only and can only be created through bulk operations on other rdd. Nonetheless,
