Will you schedule drops in Snowflake? Can you explain one approach you can use to schedule Snowflake objects?

Yes, you can schedule the dropping of Snowflake objects using Snowflake Tasks. One common approach is to create a task that runs a DROP statement at a specified time. For example, to drop a temporary table every night at 01:00 UTC:

CREATE OR REPLACE TASK drop_temp_table
  WAREHOUSE = my_wh
  SCHEDULE = 'USING CRON 0 1 * * * UTC'
AS
  DROP TABLE IF EXISTS temp_sales;

Enable the task with ALTER TASK drop_temp_table RESUME;. Snowflake’s task scheduler supports cron expressions, so you can schedule any object lifecycle operation (DROP, TRUNCATE, ARCHIVE) similarly. If you need more complex logic, wrap the DROP in a stored procedure and call it from the task. This keeps your environment clean and automates maintenance without manual intervention.
