7.3.2. Enable Receiver Prefetch

To enable a receiver to prefetch messages, set its capacity to a value greater than 0.
For example, the following code creates a receiver and enables prefetching of up to 100 messages:
Python
import sys
from qpid.messaging import *
  
connection = Connection("localhost:5672")
connection.open()
ssn = connection.session()
    
prefetchingReceiver = ssn.receiver("testqueue; {create:always}");
prefetchingReceiver.capacity = 100
