A Python Kestrel library
This library extends the Client class in the python-memcached library to add support for the non-memcache calls that kestrel supports like: config, reload, and shutdown.
You should only send strings through to the queue, if not the python-memcached library will serialize these objects and since kestrel ignores the flags supplied during a set operation, when the object is retrieved from the queue it will not be unserialized.
Adding an job to the queue:
q = kestrel.Client(servers=['127.0.0.1:22133']) q.add('test_queue', 'some test job') q.close() # disconnect the client
Read a job from the queue:
job = q.get('test_queue')
Peek at the next job in line:
job = q.peek('test_queue')
Reliably read a set of jobs from the queue:
while True: job = q.next('test_queue', timeout=10) # marks the last job as complete and gets a new one, also waits 10 seconds if no jobs are currently in the queue if job is not None: try: #process job except: q.abort('test_queue') # mark the job as failed.
q.finish('test_queue') # mark the last job a complete
