Decription

About

Radical is a RPC library that allows you to have cross-service communication out of the box.

It can serve as a replacement for Celery.

Radical has out-of-the-box integration with Django and also supports asyncio, but can be used without it.

Radical is easily extensible with custom transports and serializers.

Available transports:

  • Redis
  • Postgres

Default and recommended transport is Redis.

Available serializers:

  • JSON
  • Pickle

Default and recommended serializer is Pickle.
