  "definition": "A retry budget limits repeated request attempts within an explicitly defined operation, client or service scope.",
  "note": "A per-request allowance and an aggregate per-client policy constrain different populations of work. The budget contract must state its scope, accounting rule and reset or replenishment conditions. [sre-overload]\n\nBackoff changes timing; a budget controls admission. Neither establishes cancellation of an earlier storage operation or safe replay of its effects. [sre-cascading]",
