An Effect is a description of what the runtime needs to do after the command is handled. You can think of it as a set of instructions you are passing to the runtime, which will process the instructions on your behalf.

Each component defines its own effects, which are a set of predefined operations that match the capabilities of that component.

A Workflow Effect can either:

• update the state of the workflow
• define the next step to be executed (transition)
• pause the workflow
• end the workflow
• fail the step or reject a command by returning an error
• reply to incoming commands
