Overview

Vinay, a Data Engineer at GlobalMart, struggled with manually updating sales data daily. Seeking automation, he consulted Rahul, the Senior Architect, who introduced Snowflake Tasks for scheduling SQL execution. Vinay learned about interval-based, CRON-based, and serverless tasks, along with task dependencies forming DAGs for sequential execution. Rahul also explained activation, modification, and best practices. By the end, Vinay understood how to automate and optimize workflows using Snowflake Tasks efficiently.
