Hello All, I cannot seem to be able to set up the high water mark for PUB/SUB.
My subscriber is expected sometimes to be somewhat slower than publisher hence I want the publisher to drop the messages when subscriber is slow. I want to set up the high water mark to, say, 2 messages, so when the subscriber is behind for two messages then the publisher will start dropping them. Can you take a look at my code. The publisher sends messages once every 200ms, the subscriber reads messages once every second, the high water mark is set to 2. Hence, I expect subscriber to receive approximately every fifth message. However, my subscriber diligently reads all messages consequently and the publisher gets far ahead. http://pastebin.com/2fv525ke -- thank you!
