Pulsar Functions command line tool

The following tables list Pulsar Functions command-line tools. You can learn Pulsar Functions modes, commands, and parameters.

localrun

Run Pulsar Functions locally, rather than deploying it to the Pulsar cluster.

Name	Description	Default
auto-ack	Whether or not the framework acknowledges messages automatically.	true
broker-service-url	The URL for the Pulsar broker.
classname	The class name of a Pulsar Function.
client-auth-params	Client authentication parameter.
client-auth-plugin	Client authentication plugin using which function-process can connect to broker.
