ZMQ high water mark deprecated on 3.x.x?

Using the jzmq wrapper:

scala> import org.zeromq.ZMQ import org.zeromq.ZMQ

scala> val context = ZMQ.context(1)
context: org.zeromq.ZMQ.Context = org.zeromq.ZMQ$Context@56d58984

scala> val socket = context.socket(ZMQ.REP)
socket: org.zeromq.ZMQ.Socket = org.zeromq.ZMQ$Socket@2a5a0f9

scala> socket.getHWM()
res6: Long = -1

scala> socket.setHWM(200)

scala> socket.getHWM()
res8: Long = -1

This seems to be depreacted in version 3:

Anyone knows why? and what's the alternative to set a HWM using jzqm + zmq3?

Solution

  • Have a look at: http://zeromq.org/docs:3-1-upgrade

    In zeromq 3.2 HWM has been split into send and receive high water mark: ZMQ_SNDHWM and ZMQ_RCVHWM.

    The functions you are looking for in jzmq are:

    long    getRcvHWM()
long    getSndHWM()
void    setRcvHWM(long rcvHWM)
void    setSndHWM(long sndHWM)
