3. Spark run computations in memory

4. 1 and 3

5. 1 , 2 and 3

 

Correct Answer 5

Exp : Apache Spark is a cluster computing platform designed to be fast and general-purpose. On the speed side, Spark extends the popular MapReduce model to efficiently support more types of computations, including interactive queries and stream processing. Speed is important in processing large datasets as it means the difference between exploring data interactively and waiting minutes between queries, or waiting hours to run your program versus minutes. One of the main features Spark offers for speed is the ability to run computations in memory, but the system is also faster than MapReduce for complex applications running on disk.
