Learning Objectives

Understand Zero-Copy Cloning in Snowflake
Identify the types of objects that can be cloned
Explore cloning limitations, including privileges, external tables, and data load history

Overview

Vinay, a Data Engineer at GlobalMart, needed to experiment with customer transaction data in Snowflake but was concerned about storage costs and data duplication. Seeking guidance, he approached Rahul, the Senior Architect.

Through their conversation, Vinay learned about Zero-Copy Cloning, how it works as a metadata-only operation, and its storage efficiency. Rahul explained cloning databases, schemas, and tables, its independence from the source, and common limitations. Vinay also discovered how cloning integrates with Time Travel for historical snapshots, making experimentation cost-effective and scalable in Snowflake.
