Overview

Vinay, a Data Engineer at GlobalMart, needed to load ADLS data into Snowflake but discovered there was no direct import option. Seeking guidance, he consulted Rahul, the Senior Architect, who introduced stages, the PUT command, and COPY INTO for efficient data loading. Through their discussion, Vinay also learned about file formats, COPY options, and load history tracking, enabling him to optimize data ingestion and ensure efficient data processing in Snowflake.
