A plugin is made of a number of components. Each component is a single kind of object in Dataiku DSS, such as a dataset, recipe, or webapp. Each component adds an additional functionality to a plugin. A plugin bundles components together as a single consistent whole.
The (non-exhaustive) list of plugin components includes:
Metric probes and checks
Scenario triggers and steps
Preparation script processors
Shared code to import in recipes or notebooks
Custom Policy Hooks
The most up-to-date list of possible components can be found in the product. In the plugin editor, click + Add > Create component. The resulting dialog shows the list of possible components. When you add a component, Dataiku DSS automatically makes the appropriate additions to the plugin directory structure, and adds some starter code to help you get started.
Structure of the plugin¶
The elements of a plugin are contained within a top-level directory that identifies the plugin. When you create a plugin from scratch (called, for example,
myplugin), that top-level directory contains:
python-libsubdirectory with a
mypluginsubdirectory that has an
__init__.pyfile that is empty of code. The
python-libdirectory is a good place to put functions that will be reused throughout the plugin.
plugin.jsonfile that describes the plugin as a whole. As a best practice, the
idelement of this JSON file should be the same as the name of the top-level directory.
As you add components to the plugin, this adds to the plugin folder structure. Each type of component has a subdirectory under the top-level directory. Each individual component has a directory that contains a JSON file that describes the component as a whole, and code files that define what the component does.
Each component generally has some configuration parameters.
