django-db-geventpool

What it is and what it does

django-db-geventpool adds a connection pooling layer to Django's PostgreSQL backend using gevent or eventlet. Instead of opening a new database connection for each request, it maintains a pool of reusable connections, reducing the overhead of connection setup and teardown in high-concurrency environments.

The package works by replacing Django's default database backend with a pooled variant. You configure it in Django settings by specifying the pool engine, setting maximum connections (default 4), and optionally the number of connections to reuse across requests. The package includes a decorator utility to clean up connections when using greenlets outside the normal request cycle (e.g., in Celery tasks).

Use it for

• Running Django under a gevent-based application server to reduce database connection churn in high-request-rate scenarios.
• Using Django with task queues that spawn greenlets, where manual connection cleanup is needed to avoid connection leaks.
• Deploying Django applications on systems with strict connection limits where connection pooling significantly improves throughput.
• Switching between psycopg2 and psycopg3 backends while maintaining gevent compatibility.

Install

django-db-geventpool on PyPI

Before you install

Low friction to install; depends only on django. Maintenance status is aging—last release was 2025-02-23 but no activity for 537 days prior, and the repository shows 189 stars with no indication of active development.

Requires gevent or eventlet to be installed separately. For Django 5.1+, native pool support must be disabled by setting 'pool': False in OPTIONS.

Quickstart

# Install
pip install django-db-geventpool

# In Django settings.py, configure the pooled backend:
DATABASES = {
    'default': {
        'ENGINE': 'django_db_geventpool.backends.postgresql_psycopg3',
        'NAME': 'mydb',
        'USER': 'postgres',
        'PASSWORD': 'password',
        'HOST': 'localhost',
        'CONN_MAX_AGE': 0,
        'OPTIONS': {
            'MAX_CONNS': 20,
            'REUSE_CONNS': 10
        }
    }
}
