Explore a conference talk on enhancing Apache Spark's reliability for cloud-native data processing using Cloud Shuffle Manager. Discover how Apple engineers Bo Yang and HAI TAO address the challenge of fault tolerance in Spark's internal shuffle data when running on Kubernetes. Learn about the innovative Cloud Shuffle Manager, which stores shuffle data replications on cloud storage, enabling Spark to read from workers in normal conditions and from cloud storage during worker failures. Gain insights into the underlying optimizations for improved shuffle performance and how this approach allows for reliable Spark application execution on Spot Instances/VMs, resulting in significant cost savings at scale. Understand the potential of this solution for enhancing the reliability and cost-effectiveness of large-scale data processing in cloud environments.
