Snowflake architecture (storage, compute, services layers) - Cheat Sheet & Quick Revision

Recall & Review

beginner

What are the three main layers of Snowflake's architecture?

The three main layers are: Storage Layer, Compute Layer, and Services Layer.

beginner

What is the role of the Storage Layer in Snowflake?

The Storage Layer stores all data in a centralized, scalable cloud storage. It separates data storage from compute, allowing independent scaling.

beginner

How does the Compute Layer in Snowflake work?

The Compute Layer runs queries and processes data using virtual warehouses. Each warehouse can scale independently without affecting others.

What functions does the Services Layer provide in Snowflake?

The Services Layer manages metadata, security, query parsing, optimization, and transaction management. It acts as the brain coordinating the system.

Why is separating storage and compute beneficial in Snowflake's architecture?

Separating storage and compute allows independent scaling, cost efficiency, and better performance by letting users pay only for what they use.

Which Snowflake layer is responsible for storing data?

A Storage Layer

B Services Layer

C Compute Layer

D Network Layer

The Storage Layer stores all data in Snowflake.

What does the Compute Layer in Snowflake use to process queries?

A Virtual Warehouses

B Cloud Storage

C Metadata Services

D Security Tokens

Compute Layer uses virtual warehouses to run queries and process data.

Which layer manages query optimization and transaction control?

A Storage Layer

B Compute Layer

C Services Layer

D User Interface Layer

The Services Layer handles query parsing, optimization, and transaction management.

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

A Faster network speed

B Requires manual backups

C More complex setup

D Independent scaling of resources

Separating storage and compute allows each to scale independently.

In Snowflake, what does a virtual warehouse represent?

A A storage container

B A compute cluster for processing

C A metadata repository

D A security protocol

A virtual warehouse is a compute cluster that processes queries.

Explain the roles of the Storage, Compute, and Services layers in Snowflake's architecture.

Think of storage as the warehouse, compute as the workers, and services as the manager.

Why does Snowflake separate storage and compute, and what benefits does this bring?

Consider how a restaurant benefits from having separate kitchens and dining areas.
