Thanks Dan,
I have updated the Clear method for parallel queue.
@Override
public void clearQueue() {
this.sender.pause();
try{
this.sender.getLifeCycleLock().readLock().lock();
for (PartitionedRegion prQ :
this.userRegionNameToshadowPRMap.values()) {
clearPartitionedRegion((PartitionedRegion) prQ);
}
this.sender.getLifeCycleLock().readLock().unlock();
}finally{
this.sender.resume();
}
}
Thanks,
Dinesh Akhand

SerialGatewaySenderQueue/ParallelGatewaySenderQueue Clear
Hi Dinesh,
I think we probably just never got around to adding a clear. I think you could
probably clear your queues just stop stopping and starting the gateway sender,
which might be the easiest thing to do here.
Regarding your code, for your parallel queue are you doing that inside of a
function? The code you have will try to clear things on a single node. The
queue also maintains some other metadata in memory. I'm not quite sure what the
effect on the queue will be if you delete the region entries without changing
that other metadata. I guess you could test it and find out.
You'll probably want to see what the effect is while the queue is actually
dispatching entries as well, because it's possible you could catch the system
in a state where it is trying to read entries from the region as you are
deleting them. Or maybe pause the queue first in your clear method?
