Optimizing Spark Performance to Reduce Cloud Compute Costs for Big Data Loads

Apache Spark is a critical tool for moving data on the cloud and has a short learning curve. However, tuning Spark jobs to enhance efficiency is relatively complex and requires a deep understanding of its functioning. Apache Spark tuning can lead to a substantial decrease in the cost since fine-tuning enables Spark to utilize all available node CPUs efficiently. It reduces cost since the charges are on a per-node per-second basis for every on-going Spark job.

The purpose of this white paper is to highlight Spark performance tuning parameters that can help data engineers understand node configurations in their clusters. It will enable them to tune their Spark jobs to minimize cloud spending and maximize the benefits of parallel computing for the jobs.

In this white paper, you will learn:

  • Spark executor model and its significance in Spark performance tuning.
  • Various Spark executor configurations, their capability to efficiently execute a Spark job, and choosing the best configuration method.
  • The best practices and recommendations for tuning the existing Spark jobs and determining which Spark job requires optimization.
  • Common errors to watch out for when tuning Spark jobs and their resolution.

The executor configuration recommended in this white paper is for a 16 node cluster with 128 GB memory. This configuration can be used as a starting point. In case of any issues, you can refer to the recommended tweaks mentioned in this white paper to make this configuration work with your data needs. Also, you can use the methods explained to calculate the ideal configurations of your nodes.
