Poison Event Quarantine: 6-Step Cheatsheet to Stop Bad Payloads Blocking Your Queue
blaizedsouza · x · 2026-09-12
A developer shares a production pattern for handling poison events: one bad payload should never stall an entire queue.
Six-step quarantine cheatsheet
- Count failures per event id
- Move the event to quarantine once past the limit
- Keep the rest of the queue flowing
- Alert on quarantine growth
- Inspect quarantined events with the raw payload
- Replay only after a fix
Core principle: a poison event is a patient, not a roadblock — quarantine the event instead of permanently disabling the source. Applies to webhooks and message-queue reliability.
