Event Flow Optimization

Event flow optimization ensures connectors remain reliable under retries, partial outages, and high-volume event spikes.

Dead letter queues (DLQ)

If you use a dead letter queue, restrict access, set a retention period, and avoid storing credentials or unnecessary personal data in entries. Redact sensitive fields before persistence. Make replay an authenticated, audited operator action and validate events again before processing.

Event deduplication

Deduplicate repeated events using deterministic keys or content hashes within a sliding window to protect downstream systems.

Data minimization and recovery

Persist only the event data needed for reliable delivery and recovery. Prefer normalized, minimal payloads over indefinite raw-event retention. If raw payload retention is necessary for a documented use case, define retention and deletion policies, encrypt stored data, and restrict access to authorized operators.

Use bounded retries with backoff and idempotent processing so transient failures can recover safely. Ensure replay does not bypass validation, authorization, deduplication, or current data-retention requirements.
