beatdrop 0.1.0a5

Simplified, scalable task scheduling with typechecking.

beatdrop

See the full Documentation.

The goal of beatdrop is to provide schedulers and schedule entries that are easy to use, extensible, scalable, and backend agnostic.

It does not run tasks or python functions on a schedule. It will simply interface with task backends to send tasks when they are due.

Installation

Install the base package with pip from PyPi.

$ pip install beatdrop

For particular schedulers and backends you will also need to install their extra dependencies.

$ pip install beatdrop[redis]

Extra dependencies for task backends:

• celery

Extra dependencies for scheduler storage:

• redis

• sql

The all extra dependency will install all extra dependencies for task backends and scheduler storage.

$ pip install beatdrop[all]

Usage

There are 2 main pieces to using beatdrop.

• Schedule Entry - holds the task definition along with scheduling info.

• Schedulers - has 2 main functions.

  • They can be run as a scheduler ie monitor and send tasks to the task backend.
  • Act as clients for reading and writing schedule entries.

Simple example:

from beatdrop import CeleryRedisScheduler, IntervalEntry
from celery import Celery

celery_app = Celery()

# Create a scheduler
sched = CeleryRedisScheduler(
    max_interval=60,
    celery_app=celery_app,
    lock_timeout=180,
    redis_py_kwargs={
        "host": "my.redis.host",
        "port": 6379,
        "db": 0,
        "password": "mys3cr3t"
    }
)
# create a schedule entry
inter = IntervalEntry(
    key="my-interval-entry",
    enabled=True,
    task="test_task",
    args=("my_args", 123),
    kwargs={
        "my_kwargs": 12.4
    },
    period=10
)

# save or update an entry 
sched.save(inter)
# list all entries, this will automatically paginate
schedule_entries = sched.list()
# retrieve a specific entry
my_inter_entry = sched.get(inter.key)
# equivalent to the line above
my_inter_entry = sched.get("my-interval-entry")
# Delete an entry from the scheduler
sched.delete(inter)
