function to initialize resources outside of the context of execution, which allows you to reuse your resources inside a sensor. Here's an example from the documentation on how to use build_resources
within a sensor: python from dagster import sensor, build_resources @sensor def my_sensor(): with build_resources({"my_db": my_db_resource}) as resources: my_db = resources.my_db # You can now use my_db to query the database ...
In this example, my_db_resource
is a resource definition that provides access to the database. The build_resources
function is used to initialize the resource within the sensor's context, allowing you to perform database queries or other operations using the resource. Remember to define your resource correctly to handle the database connection and any required authentication. This approach allows you to encapsulate the logic for interacting with the database within a resource, which can then be used consistently across different parts of your Dagster code, including within sensors.
