⟩ Explain what are the execution modes in a pipeline Stage?
A stage in a pipeline has an execution mode of either “All” or “First Match”, which controls the components that get executed if more than one component is added to a stage.
For stages with a mode of “All”, each component is called to process the message in the order in which they are configured in the stage.
For stages with a mode of “First Match”, each component is polled to indicate that it is the right component until a match is found, at which point the component that matches is executed, while the remaining components do not get executed.
