Trigger Runner Command

These actions provide ability to trigger commands through event streams.

Trigger Runner Command Actions

Unlike commands, events are not broadcast to all runners. Triggering a command with this handler causes only a single runner to execute the command.

This handler is mainly useful for development and testing when a single-partition runner is used and commands are not sent through Kafka topics.

Command

Treats input payload as a command and executes it on the runner:
