Data Processing Efficiency: Optimizing Batch Workloads on Kubernetes With Custom Schedulers - Sigmar Stefánsson, NetApp & Hichem Kenniche, NetApp Instaclustr
Friday April 4, 2025 14:30 - 15:00 BST

Kubernetes is the leading platform for deploying major data processing frameworks like Apache Spark. However, its default scheduler falls short in meeting some of the advanced and specific requirements of batch workloads.

This presentation explores the necessity and benefits of custom schedulers, with a deep dive on the implementation of Volcano and Apache YuniKorn in multi-cloud Kubernetes environments running large and complex Apache Spark applications. Discover how these tools can optimize cluster management for batch and ML workloads.
