Database Connection Pooling

# Example: pgbouncer in front of Postgres
# Configure your DATABASES['default']['HOST'] to point to pgbouncer host:port.
      

# settings.py (django-db-geventpool or similar third-party, optional)

# Example with django-db-geventpool (third-party)
# pip install django-db-geventpool

DATABASES = {
    "default": {
