Which port is used by KSQL by default?

Explanation:
KSQL exposes its REST API on a dedicated port, and by default that port is 8088. This is the port you connect to when you issue statements to the KSQL server (for example, via the CLI or HTTP requests). The Kafka broker itself typically listens on 9092, so 8088 is separate from the broker’s port. Other services often use different defaults (for example, REST Proxy on 8082 or Schema Registry on 8081), which helps avoid confusion about where KSQL is listening. If you need to change this port, you can adjust the http.port setting in the KSQL server’s configuration and restart the server.
