########## docs/ebpf-sidecar-design.md: ########## @@ -0,0 +1,605 @@ +# eBPF Sidecar Design Document + +## 1. Executive Summary + +The eBPF Sidecar Agent is a kernel-level observability component for Apache SkyWalking BanyanDB that primarily monitors **page cache miss rates** - a critical metric for database performance. High cache miss rates indicate that BanyanDB is frequently reading from disk instead of memory, directly impacting query latency and throughput. By tracking these metrics at the kernel level, we can identify performance bottlenecks and optimize storage patterns. Review Comment: It is acceptable to have ebpf only for sidecar, but please make sure this is an optional in deployment. In product cases, we should only have this through operator on-demand, because even with cache missing, in most cases, there is nothing we cam do unless optimize codes and redeploy. -- This is an automated message from the Apache Git Service.
