Optimizing Apache Spark Throughput Using Intel Optane and Intel Memory Drive Technology

Apache Spark is a popular data processing engine designed to execute advanced analytics on very large data sets which are common in today’s enterprise use cases. To enable Spark’s high performance for different workloads (e.g. machine-learning applications), in-memory data storage capabilities are built right in.

However, Spark’s in-memory capabilities are limited by the memory available in the server; it is common for computing resources to be idle during the execution of a Spark job, even though the system’s memory is saturated. To mitigate this limitation, Spark’s distributed architecture can run on a cluster of nodes, thus taking advantage of the memory available across all nodes. While employing additional nodes would solve the server DRAM capacity problem, it does so at an increased cost. Intel(R) Memory Drive Technology is a software-defned memory (SDM) technology, which combined with an Intel(R) Optane(TM) SSD, expands the system’s memory.

This combination of Intel(R) Optane(TM) SSD with Intel Memory Drive Technology alleviates those memory limitations that are inherent to Spark, by making more memory available to the operating system and to Spark jobs, transparently.
