pub const MIN_HEDGE_AFTER_MS: u64 = 1;Expand description
Validation bounds on retries.hedge.hedge_after_ms (DW-063): the
tail-latency threshold before a speculative copy is sent. Below 1 ms
is pointless (the copy would race immediately); above 5 minutes the
upstream is almost certainly dead and a retry or breaker is the
right tool, not a hedge.
