+== Kafka IO
+
+Kafka IO is supported by the APEX Kafka plugin.
+The configurations below are examples.
+APEX will take any configuration inside the parameter object and forward it to Kafka.
+More information on Kafka specific configuration parameters can be found in the Kafka documentation:
+
+* link:https://kafka.apache.org/090/javadoc/org/apache/kafka/clients/consumer/KafkaConsumer.html[Kafka Consumer Class]
+* link:https://kafka.apache.org/090/javadoc/org/apache/kafka/clients/producer/KafkaProducer.html[Kafka Producer Class]
+
+
+
+=== Kafka Input
+
+APEX will receive events from the Apache Kafka messaging system.
+The input is uni-directional, an engine will only receive events from the input but not send any event to the input.
