Exploring the Longhorn Data Plane: An Overview and Enhancements

Dive into the architecture and data path of Longhorn, a distributed block storage system designed for Kubernetes, in this Chinese-language conference talk. Explore how Longhorn provides persistent and highly available storage for stateful workloads as a Cloud Native Computing Foundation (CNCF) incubating project. Learn about upcoming enhancements to improve data plane performance, including the integration of a data engine with Storage Performance Development Kit (SPDK) for better latency and throughput. Discover the potential of Userspace Block Device Driver (ublk) as a frontend to boost performance and reduce latency, particularly beneficial for edge devices using legacy data engines. Gain insights from speaker Jing-Wei Su on Longhorn's features such as snapshots, backups, and recurring jobs, while understanding the areas for improvement in the data plane's performance.
