How to get queue size?

[ray-krow-verys]

My understanding is that the java-nats library queues up messages that the server sends and dispatches them to the provided callback consumers as fast as it can. But, there is still a queue that messages can store up in.

How can I get the size of this queue? I need to know how far behind my client is for scaling needs.

Something like:
int queueSize = nc.getPendingQueueSize();

This is available from the subscription object itself. For instance sub.getPendingMsgs(). There is also pending bytes, the max that were pending, etc..

Confirmed this works, thanks for getting back and closing this so quickly @kozlovic
