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:

tests/system/providers/google/cloud/dataplex/example_dataplex.py[source]

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

tests/system/providers/google/cloud/dataplex/example_dataplex.py[source]

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",
)

tests/system/providers/google/cloud/dataplex/example_dataplex.py[source]

create_dataplex_task_async = DataplexCreateTaskOperator(
    project_id=PROJECT_ID,
    region=REGION,
    lake_id=LAKE_ID,
    body=EXAMPLE_TASK_BODY,
    dataplex_task_id=f"{DATAPLEX_TASK_ID}-1",
    asynchronous=True,
    task_id="create_dataplex_task_async",
)

Delete a task

To delete a task you can use:

DataplexDeleteTaskOperator

tests/system/providers/google/cloud/dataplex/example_dataplex.py[source]

delete_dataplex_task_async = DataplexDeleteTaskOperator(
    project_id=PROJECT_ID,
    region=REGION,
    lake_id=LAKE_ID,
    dataplex_task_id=f"{DATAPLEX_TASK_ID}-1",
    task_id="delete_dataplex_task_async",
)

List tasks

To list tasks you can use:

DataplexListTasksOperator

tests/system/providers/google/cloud/dataplex/example_dataplex.py[source]

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:

DataplexGetTaskOperator

tests/system/providers/google/cloud/dataplex/example_dataplex.py[source]

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:

DataplexTaskStateSensor

tests/system/providers/google/cloud/dataplex/example_dataplex.py[source]

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",
)

Create a Lake

Before you create a dataplex lake you need to define its body.

For more information about the available fields to pass when creating a lake, visit Dataplex create lake API.

A simple task configuration can look as followed:

tests/system/providers/google/cloud/dataplex/example_dataplex.py[source]

EXAMPLE_LAKE_BODY = {
    "display_name": "test_display_name",
    "labels": [],
    "description": "test_description",
    "metastore": {"service": ""},
}

With this configuration we can create the lake:

DataplexCreateLakeOperator

tests/system/providers/google/cloud/dataplex/example_dataplex.py[source]

create_lake = DataplexCreateLakeOperator(
    project_id=PROJECT_ID, region=REGION, body=EXAMPLE_LAKE_BODY, lake_id=LAKE_ID, task_id="create_lake"
)

Delete a lake

To delete a lake you can use:

DataplexDeleteLakeOperator

tests/system/providers/google/cloud/dataplex/example_dataplex.py[source]

delete_lake = DataplexDeleteLakeOperator(
    project_id=PROJECT_ID,
    region=REGION,
    lake_id=LAKE_ID,
    task_id="delete_lake",
    trigger_rule=TriggerRule.ALL_DONE,
)

Create or update a Data Quality scan

Before you create a Dataplex Data Quality scan you need to define its body. For more information about the available fields to pass when creating a Data Quality scan, visit Dataplex create data quality API.

A simple Data Quality scan configuration can look as followed:

tests/system/providers/google/cloud/dataplex/example_dataplex_dq.py[source]

EXAMPLE_DATA_SCAN = dataplex_v1.DataScan()
EXAMPLE_DATA_SCAN.data.entity = (
    f"projects/{PROJECT_ID}/locations/{REGION}/lakes/{LAKE_ID}/zones/{ZONE_ID}/entities/{TABLE_1}"
)
EXAMPLE_DATA_SCAN.data.resource = (
    f"//bigquery.googleapis.com/projects/{PROJECT_ID}/datasets/{DATASET}/tables/{TABLE_1}"
)
EXAMPLE_DATA_SCAN.data_quality_spec = {
    "rules": [
        {
            "range_expectation": {
                "min_value": "0",
                "max_value": "10000",
            },
            "column": "value",
            "dimension": "VALIDITY",
        }
    ],
}

With this configuration we can create or update the Data Quality scan:

DataplexCreateOrUpdateDataQualityScanOperator

tests/system/providers/google/cloud/dataplex/example_dataplex_dq.py[source]

create_data_scan = DataplexCreateOrUpdateDataQualityScanOperator(
    task_id="create_data_scan",
    project_id=PROJECT_ID,
    region=REGION,
    body=EXAMPLE_DATA_SCAN,
    data_scan_id=DATA_SCAN_ID,
)

Get a Data Quality scan

To get a Data Quality scan you can use:

DataplexGetDataQualityScanOperator

tests/system/providers/google/cloud/dataplex/example_dataplex_dq.py[source]

get_data_scan = DataplexGetDataQualityScanOperator(
    task_id="get_data_scan",
    project_id=PROJECT_ID,
    region=REGION,
    data_scan_id=DATA_SCAN_ID,
)

Delete a Data Quality scan

To delete a Data Quality scan you can use:

DataplexDeleteDataQualityScanOperator

tests/system/providers/google/cloud/dataplex/example_dataplex_dq.py[source]

delete_data_scan = DataplexDeleteDataQualityScanOperator(
    task_id="delete_data_scan",
    project_id=PROJECT_ID,
    region=REGION,
    data_scan_id=DATA_SCAN_ID,
)

Run a Data Quality scan

You can run Dataplex Data Quality scan in asynchronous modes to later check its status using sensor:

DataplexRunDataQualityScanOperator

tests/system/providers/google/cloud/dataplex/example_dataplex_dq.py[source]

run_data_scan_async = DataplexRunDataQualityScanOperator(
    task_id="run_data_scan_async",
    project_id=PROJECT_ID,
    region=REGION,
    data_scan_id=DATA_SCAN_ID,
    asynchronous=True,
)

To check that running Dataplex Data Quality scan succeeded you can use:

DataplexDataQualityJobStatusSensor.

tests/system/providers/google/cloud/dataplex/example_dataplex_dq.py[source]

get_data_scan_job_status = DataplexDataQualityJobStatusSensor(
    task_id="get_data_scan_job_status",
    project_id=PROJECT_ID,
    region=REGION,
    data_scan_id=DATA_SCAN_ID,
    job_id="{{ task_instance.xcom_pull('run_data_scan_async') }}",
)

Also for this action you can use operator in the deferrable mode:

tests/system/providers/google/cloud/dataplex/example_dataplex_dq.py[source]

run_data_scan_def = DataplexRunDataQualityScanOperator(
    task_id="run_data_scan_def",
    project_id=PROJECT_ID,
    region=REGION,
    data_scan_id=DATA_SCAN_ID,
    deferrable=True,
)

Get a Data Quality scan job

To get a Data Quality scan job you can use:

DataplexGetDataQualityScanResultOperator

tests/system/providers/google/cloud/dataplex/example_dataplex_dq.py[source]

get_data_scan_job_result_2 = DataplexGetDataQualityScanResultOperator(
    task_id="get_data_scan_job_result_2",
    project_id=PROJECT_ID,
    region=REGION,
    data_scan_id=DATA_SCAN_ID,
)

Also for this action you can use operator in the deferrable mode:

tests/system/providers/google/cloud/dataplex/example_dataplex_dq.py[source]

get_data_scan_job_result_def = DataplexGetDataQualityScanResultOperator(
    task_id="get_data_scan_job_result_def",
    project_id=PROJECT_ID,
    region=REGION,
    data_scan_id=DATA_SCAN_ID,
    deferrable=True,
)

create_asset = DataplexCreateAssetOperator(
    task_id="create_asset",
    project_id=PROJECT_ID,
    region=REGION,
    body=EXAMPLE_ASSET,
    lake_id=LAKE_ID,

    asset_id=ASSET_ID,
)

Delete a asset

To delete a asset you can use:

DataplexDeleteAssetOperator

    region=REGION,
    lake_id=LAKE_ID,
    zone_id=ZONE_ID,
    asset_id=ASSET_ID,
