Why is spark considered as in memory computing?

Introduction to Spark In-memory Computing When we use cache() method, all the RDD stores in-memory. This reduces the space-time complexity and overhead of disk storage. The in-memory capability of Spark is good for machine learning and micro-batch processing. It provides faster execution for iterative jobs.

This term typically implies large-scale, complex calculations which require specialized systems software to run the calculations on computers working together in a cluster.

What is memory tool?

In-memory processing enables instant access to terabytes of data for real time reporting. In-memory processing is available at a lower cost compared to traditional BI tools, and can be more easily deployed and maintained. According to Gartner survey, deploying traditional BI tools can take as long as 17 months.
