schedulord (Scheduler as a Service.)

DISCLAIMER: This is just an implementation of a concept not a product ready package.

Scheduler as a service over REST API.I have written a blog post which explains the idea behind scheduler as a service.

Basic workflow implemented here is as below

• write a job in python file
• send it to server
• scheduler takes care of the REST

Sounds like a lot of work! KK then lets copy paste below examples to get started.

Installation:

There is no package available in pypi as of yet.

$ # Make a virtual env 
$ mkvirtualenv testing
$ workon testing


$ git clone https://github.com/mayuroks/schedulord
$ cd schedulord
$ pip install -r requirements.txt

Usage:

Start the webserver

$ python server.py

Start the scheduler

$ python scheduler.py

Write a job

main function is what the scheduler will execute

$ cat dummy_job_files/great.py

from datetime import datetime

def main():
    print datetime.now()

Now we are ready to send our functions over REST API.

CREATE a job

$ ipython

from utils import task_sender

task_sender(file_path='dummy_job_files/great.py', interval=5, name='great task')

great.py has been uploaded

Get all jobs

$ ipython

from requests import get
HEADERS = {'Accept': 'application/json', 'Content-Type': 'application/json'}

r = get("http://127.0.0.1:5000/jobs",headers=HEADERS)
r.json()
{u'jobs': {u'great task': {u'id': 1, u'interval': 5, u'name': u'great task'}}}

DELETE a job

$ ipython

from requests import delete
HEADERS = {'Accept': 'application/json', 'Content-Type': 'application/json'}

res = delete("http://127.0.0.1:5000/jobs/1",headers=HEADERS)

Limitations

• This is just an implementation of a concept not a product ready package.

• The scheduling is not as exclusive as cron.

• Interval can only be specified in seconds. Hours, minutes, days are not handled.

• BUGS WILL show up.
