Operational Remediation Reports

Async Queue Remediation Report

Drain a fixed backlog of arrivals against a bounded depth and turn the remaining depth into a drain, steady, or throttle remediation action.

backlog depth The backlog depth and arrivals are scalars, so the remaining capacity that drives the remediation action stays deterministic without draining a live async queue.
