Queick

A simple inmemory job-queue manager for Python.

Feature

• Written in Python only standard libraries
• Job-queue manager without redis
• Working for low-spec machines
• Retry
• Retry when network available
• Scheduling

Installation

Python version >= 3.6 is required.

pip install queick

Usage

First, launch queick worker.

$ queick

Second, prepare a job file (jobfunc.py) and an application (test.py).

# jobfunc.py
import time
def function(arg):
    time.sleep(1)
    print(arg)

# test.py
from queick import JobQueue
from jobfunc import function
from time import time

q = JobQueue()
q.enqueue(function, args=("hello",))
q.enqueue_at(time() + 5, function, args=("world",)) # Run after 5 seconds

st = SchedulingTime()
st.every(minutes=1).starting_from(time.time() + 10)
q.cron(st, function, args=(1, 2,)) # Run after 10 seconds and every 1 minute

Third, run the application.

$ python test.py

For more detailed information, please refer the documentation.

Retry on network available

Jobs inside the failed queue will be dequeued when the network status changes from disconnected to connected.

Some setups are needed to use the retry mode. First, launch queick worker with --ping-host options (details below).

$ queick --ping-host asmsuechan.com # Please prepare your own ping server, do not use this.

Second, pass an option to the method.

q.enqueue(function, args=("hello",), retry_on_network_available=True)

Options
