Producer Rate Limiting Policy


Kafka uses per broker quotas to throttle the volume of data reaching each broker.

Throttling across the cluster is not possible using default Apache Kafka.

Additionally, if you are using a hosted Kafka instance you don't have access to the Kafka configuration to set quotas.

This interceptor improves the throttling story by limiting throughput at a per Gateway scope, throttling produce throughput on either a global or per vcluster(tenant) basis.

  • BLOCK → when threshold is reached, throttle and save an error in audit.
  • INFO → when threshold is reached, do not throttle but save in audit a warn.
