pgcronner 0.1.14

Fast pgcron manager written in Rust

PGCronner

PGCronner is a simple and fast Python package written in Rust using PyO3 that helps manage PostgreSQL cron jobs. It lets you take control of your cron jobs by allowing you to add, remove, or list them easily. PGCronner uses a custom table to handle all these operations seamlessly.

The tool takes advantage of the PyO3 library—an extension module that enables interoperability between Python and Rust. This allows for an increased performance and memory safety.

Installation

First of all, you need to ensure that you have Python installed on your system. If you do not, please follow the official guide to get it up and running.

The package can be installed via pip:

pip install pgcronner

Usage

To use the package, you just need to import it into your Python script.

Here is an example of how to create a new pgcron job:

from pgcronner import PGCronner, Job

PG_URI = "postgresql://postgres:postgres@localhost:5432/postgres" 
pgcronner = PGCronner(PG_URI)

# Create a Job using the provided JobBuilder
# my_job = Job("<name>", "<schedule>", "<command>", "<source>")
my_job = Job("testjob", "*/5 * * * *", "SELECT 1;", "source")

# Pass the Job Object
pgcronner.add(job)

# Sync db table with pgcron
# !!! WARNING - DANGER ZONE !!!
# This deletes all jobs with prefix 'pgcronner' in the `cron.job` table and populates it with the jobs in `pgcronner_jobs`
# See below for implementation

pgcronner.sync()

Listing all the jobs:

jobs = pgcronner.all()
for job in jobs:
    print(job)

Retrieve one job:

job = pgcronner.one("<jobname>")

Removing a job:

# The parameter would be the job name you want to delete.
pgcronner.remove(job_name)

Django

In the examples directory there's also an example on how to add this to a Django project.
