pub(crate) const DRAIN_GRACE: Duration;Expand description
How long a stop is allowed to take before the process leaves without it.
Bounded below by pipeline::Config::max_block_age: step 1 of drain only
makes progress once the block an in-flight export is waiting on seals, and
with the listener closed nothing else will grow it. So this is a multiple of
that constant, not a number chosen freely.
