ksqlDB HOWTO: Integration with other systems 

Using ksqlDB you can pull data in from other systems (e.g. databases, JMS message queues, etc etc), and push data down to other systems (NoSQL stores, Elasticsearch, databases, Neo4j, etc etc).
This is done using Kafka Connect, which can be run embedded within ksqlDB or as a separate cluster of workers. ksqlDB can be used to create and control the connectors. For example:
CREATE SINK CONNECTOR SINK_ELASTIC_ORDERS_01 WITH (
'connector.class' = 'io.confluent.connect.elasticsearch.ElasticsearchSinkConnector',
'topics' = 'ORDERS_ENRICHED',
'connection.url' = 'elasticsearch:9200',
'type.name' = '_doc'
);
