* fix(proxy): fail parked DB lookups at a deadline and flip readiness while they stall Under a load burst with a slow authentication database every request parked inside the pod with no deadline while /health/readiness kept answering 200 (its own ping gets a fresh connection), so the load balancer kept sending traffic until the pod hit its memory limit, and the parked requests completed against the provider minutes after every client had hung up Every pre-request read (key, team, user, end user, budget, membership, organization, object permission, jwt mapping, project, proxy budget, spend counter reseed) now runs under one deadline, PROXY_DB_LOOKUP_DEADLINE_SECONDS (default 10 s). A lookup that hits it fails the request with the existing 503 "authentication database is temporarily unreachable" answer, honours allow_requests_on_db_unavailable, and never triggers the transport reconnect (the transport is fine, the query is slow), which is what turned the repro's stall into "too many clients". Writes stay unbounded A deadline hit marks the pod stalled for PROXY_DB_LOOKUP_STALL_WINDOW_SECONDS (default 30 s, 0 disables), during which /health/readiness answers 503 with "db": "stalled" behind the same fail-open gate, so the pod leaves rotation before it fills its memory. The existing litellm_in_flight_requests gauge already exposes the parked set on /metrics The deadline is enforced on the wall clock: bounded_db_lookup waits on the lookup task with asyncio.wait and raises DBLookupDeadlineExceeded when the deadline passes even if the lookup absorbs its cancellation, where asyncio.wait_for on 3.12+ would sit on the cancelled task for as long as it takes The failure spend-log row no longer re-runs the key and team lookups when the failure itself is a database connection or deadline error, so a request that hit the deadline is answered after one deadline instead of two * fix(proxy): bound the spend counter gate wait and narrow the stalled lookup shortcut Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com> * fix(proxy): keep the global spend lookup on the prisma client handle Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com> --------- Co-authored-by: mateo-berri <277851410+mateo-berri@users.noreply.github.com> Co-authored-by: yassin <yassin@berri.ai> Co-authored-by: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com> |
