How can I set conditional child task to continue or pause based on status (success/failure/warning) of a parent task in SnowFlake data warehouse?

Currently evaluating Snowflake database for our data warehouse, based on their documentation, Looks like Snowflake do have support for scheduling Tasks and create task tree hierarchy.

Snowflake does seem to support conditional child task but I can't figure out setting up a conditional task to continue or pause child task based on parent task success/warning or failure.

## Sample Task tree creation in Snowflake

// Create a child task
CREATE OR REPLACE TASK DATA_IMPORT
WAREHOUSE = COMPUTE_WH
SCHEDULE = ‘60 MINUTE’

AS
INSERT INTO CUSTOMERS2 SELECT * FROM CUSTOMERS;

// Create a child task
CREATE OR REPLACE TASK DATA_IMPORT
WAREHOUSE = COMPUTE_WH
WHEN 1=2  // SAMPLE CONDITION
AFTER DATA_IMPORT
AS
CALL POST_PROCESS_STORED_PROCEDURE( );

Would appreciate any pointers if you have more knowledge on Snowflake Task structure.
Thank you

CREATE TASK:

> AFTER string [ , string , ... ]
>
> Specifies one or more predecessor tasks for the current task. Use this option to create a DAG of tasks or add this task to an existing DAG. A DAG is a series of tasks that starts with a scheduled root task and is linked together by dependencies.
>
> A task runs after all of its predecessor tasks have finished their own runs successfully (after a brief lag).
