"""Executes a Census sync for a given ``sync_id`` and polls until that sync completes, raising
an error if it is unsuccessful.
It outputs a :py:class:`~dagster_census.CensusOutput` which contains the details of the Census
sync after it successfully completes.
It requires the use of the :py:class:`~dagster_census.census_resource`, which allows it to
communicate with the Census API.
**Examples:**
.. code-block:: python
from dagster import job
from dagster_census import census_resource, census_sync_op
my_census_resource = census_resource.configured(
{
"api_key": {"env": "CENSUS_API_KEY"},
