Sliding Window

Sliding Window is an implementation of a process worker pool that constantly keeps a given number of running processes. The implementation is based on python's multiprocessing module.

Install

Using Pip

Run the command:

pip install mp_sliding_window

Instaling from the source

You can clone the repository and install:

git clone https://github.com/jalpedrinha/slidingwindow.git
cd slidingwindow && python setup.py install

Compatibility

Tested for python2.7+

Supports postgresql and sqlite3.

Getting Started

We start by providing the tasks we'll be running using any iterable. In this case we'll use a generator pattern because it makes sense in the context of a sliding window.

def generator():

x = 0 while x < 10: x += 1 yield x

Next we provide the function we want to run in each process

def square(x):

print x*x

The last step is to create a sliding window with a given size, target and tasks. After invoking start the sliding window will run until there are no more tasks.

sl = SlidingWindow(size = 5, target=square, tasks=generator()) sl.start()
