   transfer of metrics in any format via HTTP, it is recommended to use

+- Input plugins are no longer limited from adding metrics when the output is
+  writing, and new metrics will move into the metric buffer as needed.  This
+  will provide more robust degradation and recovery when writing to a slow
+  output at high throughput.
+
+  To avoid over consumption when reading from queue consumers: `kafka_consumer`,
+  `amqp_consumer`, `mqtt_consumer`, `nats_consumer`, and `nsq_consumer` use
+  the new option `max_undelivered_messages` to limit the number of outstanding
+  unwritten metrics.
