Procrastinate

Spec sheet

Purpose

Procrastinate is an open-source distributed task processing library for Python that uses PostgreSQL to store task definitions, manage locks, and dispatch tasks.Read 9 Oct 2026 · procrastinate.readthedocs.io

Intended users

The documentation presents Procrastinate for Python applications that need to defer work to workers, including applications using Django or ASGI frameworks.Read 9 Oct 2026 · procrastinate.readthedocs.io

Database requirement

Procrastinate relies on PostgreSQL 13 or later to store and manage jobs.Read 9 Oct 2026 · procrastinate.readthedocs.io

Django integration

The Django integration can use Django database settings, load tasks from apps, provide models and admin pages for Procrastinate tables, and supply Django migrations.Read 9 Oct 2026 · procrastinate.readthedocs.io

Error reporting

When a job raises an error, Procrastinate logs the error with `exc_info`; the documentation names Sentry logging integration and Google Cloud as tools that can collect these errors.Read 9 Oct 2026 · procrastinate.readthedocs.io

Execution modes

It supports synchronous and asynchronous code, and the documentation recommends asynchronous use when possible.Read 9 Oct 2026 · procrastinate.readthedocs.io

Installation

The quickstart installs Procrastinate in a Python virtual environment with `pip install procrastinate`.Read 9 Oct 2026 · procrastinate.readthedocs.io

Locks and priorities

Jobs sharing a lock are processed one at a time, ordered by descending priority and then ascending creation time.Read 9 Oct 2026 · procrastinate.readthedocs.io

Monitoring

The command-line interface provides health checks, and its interactive shell can inspect and administer jobs, tasks, queues, and locks.Read 9 Oct 2026 · procrastinate.readthedocs.io

Monitoring limitation

The documentation says the administration shell is experimental and that an administration web portal is not yet available.Read 9 Oct 2026 · procrastinate.readthedocs.io

Retries

Tasks can use retry strategies with retry limits, constant, linear, or exponential delays, and exception filters.Read 9 Oct 2026 · procrastinate.readthedocs.io

Scheduling

Jobs can be scheduled to run once in the future or after a specified delay, and tasks can also be launched periodically.Read 9 Oct 2026 · procrastinate.readthedocs.io

Windows support

Procrastinate is manually tested and known to work on Windows, but its documentation advises using a Unix-like system in production because workers may stop abruptly and Windows has no automated tests.Read 9 Oct 2026 · procrastinate.readthedocs.io
