django-tenants-smart-executor 0.2.0

Executors for django-tenants which check whether any migrations need running before running them, making it faster.

Django Tenants Smart Executor

When using django-tenants, migrations can be quite slow when you have a lot of tenants. This is the case even if there are actually no migrations to run. This package provides executors that skip running the migrations for a tenant if there are no migrations to run. If there's no migratuons to run, the schema_migrated signal is still triggered.

Installation

Install using pip (or your package manager of choice):

pip install django-tenants-smart-executor

And configure the GET_EXECUTOR_FUNCTION in your settings.py:

GET_EXECUTOR_FUNCTION = "django_tenants_smart_executor.load_executor"

Usage

When you run migrations when all tenants are migrated, the output will look something like this:

$ python manage.py migrate_schemas
No migrations needed for schema public, only triggering signals
No migrations needed for schema test, only triggering signals

The multiprocessing executor is also supported.

$ python manage.py migrate_schemas --executor multiprocessing
No migrations needed for schema public, only triggering signals
No migrations needed for schema test, only triggering signals
