Is it possible to limit no. of consumers for a queue?

[Teja-Cuber]

Hi,
Due to an ongoing requirement, I have been trying to limit the consumption of messages to a controllable level where I have added the following settings to the consumers.
visibilityTimeout, heartBeatInterval & pollingWaitTimeMs.
This has overall reduced the load on system due to concurrent consumers and I am aware of the fact that it is not possible to limit the number of consumers for a queue, but is there any other possibility to do it through this library apart from the settings above?
