Demo: Multi-Node ksqlDB Deployment

This demo shows how to set up a multi-node ksqlDB cluster (with multiple ksqlDB API servers).

Start ksqlDB API server

$ ./bin/ksql-server-start config/ksql-server.properties
...
Server 0.27.2 listening on http://0.0.0.0:8088

$ ./bin/ksql http://0.0.0.0:8088
...
CLI v0.27.2, Server v0.27.2 located at http://0.0.0.0:8088
Server Status: RUNNING
...
ksql> server
http://0.0.0.0:8088

Leave the ksql session open.

Start Another Instance of ksqlDB API server

export KSQL_OPTS="-Dlisteners=http://0.0.0.0:8188"
$ ./bin/ksql-server-start config/ksql-server.properties
...
Server 0.27.2 listening on http://0.0.0.0:8188

Change the current ksqlDB API server to http://0.0.0.0:8188.

ksql> server http://0.0.0.0:8188
Server now: http://0.0.0.0:8188
ksql> server
http://0.0.0.0:8188
