Does Zero-Copy Cloning operate on more than just the metadata?

1. True

2. False

3. Only for certain types of data

4. Depends on data size

The correct answer is: False

The concept of Zero-Copy Cloning in Snowflake allows users to create a clone of a database, schema, or table without duplicating the underlying data. This means that the clone operates primarily on metadata, which includes the structural definitions and processes associated with the database objects. The original data remains untouched, and the clone points to the same storage location as the original data until any modifications are made. After changes occur, the respective data blocks are copied to maintain data integrity. Since Zero-Copy Cloning does not involve copying the actual data when the clone is created, the correct response indicates that it operates on metadata alone, not on duplicating the underlying data. This efficient use of storage and resources allows for quick and space-efficient data manipulation without incurring additional storage costs associated with duplicating large datasets.
