Xircuits Context

Aside from passing data between components by connecting the outPort to inPort, data can be passed between components via Context (ctx). This is useful for variables that are constantly used in most if not all components in a workflow (such as SparkSession), so you don't have to link it multiple times.

In the Python component code side, the ctx is added to the base component execute() method. A component that would like to add or access data from ctx can treat it as a normal dict. Here's an example of a component that uses it:

from xai_components.base import Component, xai_component
@xai_component()
class HelloContext(Component):
        
    def execute(self, ctx):
        context_dict = {"new ctx": "Hello Xircuits!"}
        ctx.update(context_dict)
