Google Dataplex Operators¶
Dataplex is an intelligent data fabric that provides unified analytics and data management across your data lakes, data warehouses, and data marts.
For more information about the task visit Dataplex production documentation <Product documentation
Create a Task¶
Before you create a dataplex task you need to define its body. For more information about the available fields to pass when creating a task, visit Dataplex create task API.
A simple task configuration can look as followed:
EXAMPLE_TASK_BODY = {
"trigger_spec": {"type_": TRIGGER_SPEC_TYPE},
"execution_spec": {"service_account": SERVICE_ACC},
"spark": {"python_script_file": SPARK_FILE_FULL_PATH},
}
With this configuration we can create the task both synchronously & asynchronously:
DataplexCreateTaskOperator
create_dataplex_task = DataplexCreateTaskOperator(
project_id=PROJECT_ID,
region=REGION,
lake_id=LAKE_ID,
body=EXAMPLE_TASK_BODY,
dataplex_task_id=DATAPLEX_TASK_ID,
task_id="create_dataplex_task",
)
create_dataplex_task_async = DataplexCreateTaskOperator(
project_id=PROJECT_ID,
region=REGION,
lake_id=LAKE_ID,
body=EXAMPLE_TASK_BODY,
dataplex_task_id=DATAPLEX_TASK_ID,
asynchronous=True,
task_id="create_dataplex_task_async",
)
Delete a task¶
To delete a task you can use:
delete_dataplex_task = DataplexDeleteTaskOperator(
project_id=PROJECT_ID,
region=REGION,
lake_id=LAKE_ID,
dataplex_task_id=DATAPLEX_TASK_ID,
task_id="delete_dataplex_task",
)
List tasks¶
To list tasks you can use:
list_dataplex_task = DataplexListTasksOperator(
project_id=PROJECT_ID, region=REGION, lake_id=LAKE_ID, task_id="list_dataplex_task"
)
Get a task¶
To get a task you can use:
get_dataplex_task = DataplexGetTaskOperator(
project_id=PROJECT_ID,
region=REGION,
lake_id=LAKE_ID,
dataplex_task_id=DATAPLEX_TASK_ID,
task_id="get_dataplex_task",
)
Wait for a task¶
To wait for a task created asynchronously you can use:
dataplex_task_state = DataplexTaskStateSensor(
project_id=PROJECT_ID,
region=REGION,
lake_id=LAKE_ID,
dataplex_task_id=DATAPLEX_TASK_ID,
task_id="dataplex_task_state",
)
