5.3. Ngenea Worker Plugins

Warning

This feature is currently in alpha

When creating workflows on Ngenea Hub, there might not be a pre-existing task that matches the specific behavior required for a particular workflow. To address this issue, Ngenea Hub now supports the ability to add custom plugin tasks to any instance of Ngenea Worker, allowing you to define tasks that cover the missing behavior.

These custom tasks are defined using Celery, a popular task distribution framework. You can read more about Celery and how it works here: https://docs.celeryq.dev/en/stable/.
