+
+The Kafka adapter exposes a Kafka topic as a STREAM table, so it can be query
using
+[Calcite Stream SQL]({{ site.baseurl }}/docs/stream.html). Note that the
adapter will not attempt to scan all topics,

+
+{% highlight json %}
+{
+ "version": "1.0",
+ "defaultSchema": "KAFKA",
+ "schemas": [
+ {
+ "name": "KAFKA",
+ "tables": [
+ {
+ "name": "TABLE_NAME",
+ "type": "custom",
+ "factory": "org.apache.calcite.adapter.kafka.KafkaTableFactory",
+ "row.converter": "com.example.CustKafkaRowConverter",
+ "operand": {
+ "bootstrap.servers": "host1:port,host2:port",
+ "topic.name": "kafka.topic.name",
