Hi, I would like to start a discussion thread on KIP-1291. In this KIP, we aim to expose all 7 Linux I/O metrics from /proc/self/io instead of just the current 2 (read_bytes and write_bytes). The 5 additional metrics (rchar, wchar, syscr, syscw, cancelled_write_bytes) enable operators to diagnose cache effectiveness, write amplification, and I/O pattern inefficiencies.
