+Ingesting from Kafka 8
+---------------------------------
+
+
+Continuing from the Kafka 7 examples, to support Kafka 8, a couple changes need to be made:
+
+- Update realtime node's configs for Kafka 8 extensions
+  - e.g.
+    - `druid.extensions.coordinates=[...,"io.druid.extensions:druid-kafka-seven:0.6.121",...]`
+    - becomes
+    - `druid.extensions.coordinates=[...,"io.druid.extensions:druid-kafka-eight:0.6.121",...]`
+- Update realtime task config for changed keys
+  - `firehose.type`, `plumber.rejectionPolicyFactory`, and all of `firehose.consumerProps` changes.
