JMS Consumer Processing Mode

Hi,

Can someone explain the Processing Mode available in JMS Consumer Snap? There is a reference to ‘STOP’ message in the doc but no explanation of what is this ‘STOP’ message or how to generate this.

And what is the significance of the message count here? Does that means, message count is the hard limit to stop the pipeline?

How the pipeline will enable again? How and when the message count ‘counter’ will reset again to 0?

Any pointers will helpful.

Thanks
