Struct RuntimeSection 

pub struct RuntimeSection {
    pub scheduler_threads: usize,
    pub jit_threshold: Option<u32>,

Engine runtime settings from [runtime].

Fields

scheduler_threads: usize

Number of scheduler worker threads.

jit_threshold: Option<u32>

JIT compilation threshold: recorded calls to one (module, function, arity) before beamr compiles it.

Absent means beamr applies its own default; the server invents no value. Read aion::RuntimeConfig::jit_threshold before setting it — a large value defers compilation past any realistic workload but is not a JIT off-switch.

query_timeout_ms: Option<u64>

Engine reply deadline for workflow queries, in milliseconds. REQUIRED — the server always mounts /workflows/query, so the query reply deadline must be an explicit operator decision; there is no default. The engine builder is equally explicit-no-default.

workloop_sweep_interval_ms: Option<u64>

How often the engine sweeps its registered workloops, in milliseconds.

This is the DEAD-MAN DETECTION interval, not a scheduling precision knob: a loop’s cadence window is checked once per sweep, so the sweep interval bounds how late a fire or a missed window can be noticed. Cost scales with the number of REGISTERED loops, not with how many are due.

stop_drain_timeout_ms: Option<u64>

The engine stop’s drain bound, in milliseconds (AE-017).

A NO-PROGRESS bound: when the server stops, each engine worker thread (cleanup executor, exit drainer, exit-callback dispatcher) is drained, and the drain fails only when that worker has completed NOTHING for this long — the clock restarts on every completed job. A loaded box that is still finishing callbacks is never called a wedge; a callback that is genuinely stuck is named within this window of sticking, with the in-flight age and queue depth in the log. Omitted → 30 s (the estate’s ruled patience of one deploy); zero is refused.
