What is a Connector in ksqlDB

A connector is a mechanism to import or export data from your ksqlDB cluster to external systems.

For example, you can use the “change data capture (or CDC)” pattern on databases like PostgreSQL, consume tweets from social media sites like Twitter , or notify through messages in Slack when a record is produced in Kafka .

ksqlDB uses the Apache Kafka Connect framework — this means you can run any connector implemented for that framework.
