Quota and SpikeArrest solve different problems and behave differently. SpikeArrest smooths instantaneous rate at the message processor level; Quota counts against a distributed counter over a window. Configuring one where you needed the other produces exactly the symptom this customer had.
Partners were receiving throttling responses well below their contracted call volume, while a genuine traffic burst from a single partner still reached the backend and degraded it. SpikeArrest was set at a rate that assumed a single message processor, and the Quota policy was not configured as distributed or synchronous, so counts diverged across processors.
Apigee X fronting reservation and inventory backends, with partner-tier quotas defined in API products.
AceMQ mapped the intended commercial rate limits onto the correct policy for each behavior — burst smoothing versus contractual volume — and corrected the counter distribution settings. We then validated with a load profile that reproduced both a steady partner load and a realistic burst.
Legitimate partner traffic stopped being rejected below contracted volume, and burst traffic is now smoothed at the gateway instead of reaching the backend intact.
