GRADUAL-ROLLOUT

Gradual rollout. See Enterprise Integration Patterns.

Definition

Gradual rollout — progressive deployment of an EDI change to a subset of partners (1%, 10%, 50%, 100%) to limit blast radius in case of regression.

Origin

Pattern documented by feature flags (LaunchDarkly, GrowthBook) and SRE engineering. Adapted to EDI by conditional routing-rule on the partner code.

Use

INVOIC mapping update: the new version is activated on 10 pilot partners for 7 days, rejection rates are monitored, then extended to 50%, then 100% if no incident.
