XRP - In-Kernel Storage Functions with eBPF

Explore a groundbreaking conference talk on XRP, an innovative framework for executing user-defined storage functions in the NVMe driver using eBPF. Discover how this award-winning research addresses the significant overhead of the Linux kernel storage stack in the era of microsecond-scale NVMe storage devices. Learn about XRP's ability to safely bypass most of the kernel's storage stack while preserving file system semantics. Examine the implementation of XRP in two key-value stores, BPF-KV and WiredTiger, and understand how it substantially improves throughput and latency. Gain insights into the future of storage optimization for high-performance computing environments in this 15-minute presentation from OSDI '22.
