}Expand description
Per-upstream circuit breaker knobs (DW-015). All fields default; a
breaker: block with no keys enables the breaker with the defaults.
Frozen semantics (see the breaker module docs):
- The breaker gates the WHOLE upstream (all endpoints); per-endpoint ejection (DW-012) is an independent layer beneath it.
- It opens on
consecutive_failuresconsecutive failures (5xx or transport) OR an in-window error ratio >=error_ratioonce at leasterror_volumeobservations are in the 60 s window. - While open, requests fail fast with 503 and a
Retry-Afterheader (seconds until half-open); in-flight requests complete normally. - After
open_msa half-open probe (half_open_probesconcurrent trials) closes the breaker on success or re-opens it on failure.
Fields§
§consecutive_failures: u32Consecutive failures (5xx + transport) that open the breaker (default 5).
error_ratio: f64In-window error ratio in (0, 1] that opens the breaker once
error_volume observations exist (default 0.5).
error_volume: u32Minimum observations in the 60 s window before the ratio is evaluated (default 20).
open_ms: u64Cooling-off period in milliseconds before a half-open probe is admitted (default 30000).
half_open_probes: u32Concurrent trial requests admitted in half-open (default 1).
