Cerbero.Severity (cerbero v0.1.0)

Copy Markdown View Source

severity(lock, cost, scale, traffic, config, multiplier).

Lock-queue damage tracks traffic, not table size; rewrite/scan damage tracks rows and bytes. The multiplier is staleness headroom (thresholds shrink as the snapshot ages). Unknown scale is unbounded, never small. An ACCESS EXCLUSIVE operation is never silent: the floor is :info.
