Snowflake vs traditional data warehouses - Quick Revision & Key Differences

Recall & Review

beginner

What is a key difference between Snowflake and traditional data warehouses in terms of architecture?

Snowflake uses a cloud-native, multi-cluster shared data architecture separating storage and compute, while traditional data warehouses often combine storage and compute tightly.

beginner

How does Snowflake handle scaling compared to traditional data warehouses?

Snowflake can scale compute resources up or down independently and automatically, allowing multiple users to query without performance impact, unlike traditional warehouses which often require manual scaling.

intermediate

What is a benefit of Snowflake's separation of storage and compute?

It allows users to pay only for the compute and storage they use, improving cost efficiency and flexibility compared to traditional warehouses where resources are bundled.

beginner

Why is Snowflake considered easier to manage than traditional data warehouses?

Snowflake is fully managed in the cloud, handling infrastructure, tuning, and maintenance automatically, while traditional warehouses often require manual setup and ongoing management.

intermediate

How does Snowflake support concurrent users compared to traditional data warehouses?

Snowflake's multi-cluster architecture allows many users to run queries simultaneously without slowing each other down, unlike traditional warehouses where concurrency can cause bottlenecks.

What does Snowflake separate to improve flexibility and cost?

A Data and metadata

B Storage and compute

C Users and roles

D Network and security

Snowflake separates storage and compute, allowing independent scaling and cost control.

Which feature allows Snowflake to handle many users querying at once without slowing down?

A Multi-cluster shared data architecture

B Manual tuning

C Single-node processing

D On-premises hardware

Snowflake's multi-cluster architecture supports high concurrency without performance loss.

Traditional data warehouses usually require what kind of scaling?

A No scaling needed

B Automatic and independent

C Manual and combined storage-compute

D Cloud-based scaling

Traditional warehouses often need manual scaling and combine storage and compute resources.

Which is a management advantage of Snowflake over traditional warehouses?

A Fully managed cloud service

B No automatic backups

C Needs on-premises setup

D Requires manual tuning

Snowflake is fully managed, reducing administrative overhead.

How does Snowflake charge users?

A Fixed monthly fee regardless of usage

B Based on number of users only

C Only for storage, compute is free

D Based on actual compute and storage used

Snowflake charges based on actual compute and storage consumption, improving cost efficiency.
