Why data sharing eliminates data copies in Snowflake - Quick Recap

Recall & Review

beginner

What is data sharing in Snowflake?

Data sharing in Snowflake allows one account to provide access to its data directly to another account without copying or moving the data.

beginner

How does Snowflake avoid creating data copies when sharing data?

Snowflake uses a secure pointer to the original data instead of duplicating it, so shared data is accessed live without making copies.

beginner

Why is eliminating data copies beneficial?

It saves storage space, reduces costs, ensures data is always up-to-date, and simplifies data management.

intermediate

What role does Snowflake's architecture play in data sharing?

Snowflake's architecture separates storage and compute, enabling multiple accounts to access the same data storage without duplication.

beginner

Can data sharing in Snowflake be controlled for security?

Yes, data providers control what data is shared and who can access it, ensuring secure and governed sharing.

What does Snowflake use to share data without copying it?

A A compressed backup file

B A secure pointer to the original data

C A duplicate copy of the data

D A local cache on the receiver's system

Snowflake shares data by providing a secure pointer to the original data, avoiding duplication.

Which benefit is NOT a reason why eliminating data copies is good?

A Reduces management complexity

B Ensures data is always current

C Saves storage space

D Increases data duplication

Eliminating data copies reduces duplication, not increases it.

How does Snowflake's architecture support data sharing?

A By separating storage and compute layers

B By copying data to each user account

C By encrypting data multiple times

D By storing data only on local machines

Snowflake separates storage and compute, allowing shared access to the same storage.

Who controls what data is shared in Snowflake?

A Snowflake support team

B The data consumer

C The data provider

D Any user with access

The data provider controls sharing permissions and data visibility.

What happens if data is updated by the provider after sharing?

A Consumers see the updated data immediately

B Consumers keep the old copy forever

C Data sharing stops automatically

D Consumers must request a new copy

Because data is shared live, updates are visible immediately to consumers.
