15 Key Snowflake Features: The Ultimate Guide

As organizations generate and store more data than ever, the need for a flexible, high-performing solution to manage, analyze, and secure that data has become critical. Enter the data cloud—a modern approach that unifies data across sources and scales effortlessly to meet businesses' evolving needs.

Among the leading platforms in this space is Snowflake, a cloud-based data warehouse designed for storage and collaboration, governance, and intelligent insights. Whether handling production workloads or running analytics for testing purposes, Snowflake makes it easy to connect disparate data sources and users in a single, secure environment.

In this article, we'll explore some of Snowflake's most powerful features and explain why it has quickly become a go-to choice for organizations building in the modern data cloud.

What Is Snowflake?

Snowflake is a cloud-based data warehousing platform that provides a fully managed solution for storing and analyzing vast amounts of data. It doesn't utilize existing database technology or big-data software platforms, such as Hadoop, for data processing. Instead, Snowflake has an entirely new SQL query engine combined with a unique cloud-native architecture.

Snowflake can seamlessly integrate with popular cloud providers such as AWS, Azure, and Google Cloud Platform. It can automatically be scaled up or down, ensuring efficient data loading, integration, and analysis. This allows multiple users to run numerous workloads simultaneously without concerns about resources. The platform efficiently manages multiple compute nodes to process data in parallel, enabling high concurrency and workload isolation.

What Are the Core Components of Snowflake Architecture?

Snowflake architecture combines features of shared-disk and shared-nothing database architectures to leverage the benefits of each. Let's examine the details of these approaches.

• Shared-disk Architecture: This architecture utilizes multiple cluster nodes (processors) that can access all the data stored on a shared memory disk. These nodes have CPU and memory but no disk storage of their own. Instead, they communicate with a central storage layer to retrieve data.
• Shared-nothing Architecture: Data is partitioned and distributed among different nodes, which process the data independently and in parallel. Each node has its own disk storage, and no central storage layer exists.

Snowflake provides fast results by combining the advantages of the two database architectures: shared-disk and shared-nothing. It uses a central repository, like a shared-disk database, where data is stored and accessible from all compute nodes.

However, Snowflake also employs MPP (massively parallel processing) compute clusters for processing queries, similar to a shared-nothing architecture, where each node stores a portion of the data set locally. This distributed architecture allows Snowflake to efficiently process queries across multiple compute nodes, enabling rapid data retrieval and concurrency.

Snowflake architecture mainly consists of three layers: cloud services, query processing, and storage. Let's take a look at each of them in detail:

Database Storage Layer

The data in Snowflake is organized into multiple micro-partitions, which are compressed and optimized internally for better performance. It follows a columnar format for storage, resulting in significantly faster querying. Snowflake utilizes the cloud to store data objects and maintain privacy by keeping them hidden and inaccessible to others. Access to these objects is only possible through SQL query operations using Snowflake. Each Snowflake account maintains strict network security protocols to protect stored data content and ensure authorized access.

Query Processing Layer

This layer executes queries against the data in the storage layer. Query processing is carried out by Virtual Warehouses, which are computing units consisting of multiple nodes featuring Snowflake-provisioned CPU and memory.

Snowflake supports the creation of multiple Virtual Warehouses, allowing you to allocate resources based on the specific workload. These warehouses can be started or stopped at any time and scaled up or down without affecting running queries.

Snowflake processes queries by distributing them across multiple compute nodes, optimizing query execution time and resource usage. These compute clusters handle user requests concurrently, maintaining high performance even with large workloads.

Cloud Services Layer

This layer manages authentication, security, data management, and query optimization operations. It uses stateless computing resources that operate across different availability zones and provide highly accessible and usable information. The Cloud Service layer offers a SQL client interface to interact with the Snowflake platform. This interface supports DDL and DML to define database objects and query data.

Additionally, this layer manages user requests related to session control, metadata management, and the sharing of data content between Snowflake accounts, all while enforcing network security policies.

With a detailed understanding of Snowflake's architecture, let's explore the key features that make Snowflake a leading cloud data platform.

What Are the Essential Snowflake Features for Modern Data Teams?

Snowflake offers several distinctive features that differentiate it from other cloud-based data warehouse solutions. Here are a few of them:

1) Near-Zero Management

Snowflake offers near-zero management because it's a cloud-based, fully managed platform that requires no hardware to select, install, configure, or manage. The platform features auto scaling, auto suspend, and in-built performance tuning capabilities that eliminate manual administration. This means you can focus on data and analytics instead of spending time on resource management.

2) Scalability

With Snowflake's auto-scaling feature, the warehouse size can automatically adjust based on demand. This ensures that the system can efficiently handle varying workloads without manual intervention. Snowflake continuously monitors the workload, including query complexity, resource usage, and concurrency, to determine scaling actions.

The ability to add or remove multiple compute nodes dynamically enables Snowflake to process data and scale resources precisely according to user requests and workload needs.

3) Cloning

The cloning feature, also known as zero-copy cloning, is a fast and cost-efficient way to create a copy of any table, schema, or the entire database. The clone is a logical copy of the original object and points back to the original data. This means that cloning is instantaneous and doesn't use additional memory until changes are made to the new copy.

4) Time Travel

With Snowflake Time Travel, you can easily access historical data that may have been altered or deleted within a specific timeframe. This enables you to retrieve previous versions of data, providing a comprehensive view of data changes over time. In addition, Time Travel simplifies auditing and compliance requirements by providing precise control over data versions.

5) Fail-Safe

Snowflake incorporates a fail-safe feature that allows for the recovery of any data that has been lost or damaged due to critical operational failures. During the Time Travel period, Snowflake stores deleted or updated data in the history for up to 90 days. Once this period elapses, the fail-safe stores the data for an additional seven days as a backup. This approach ensures a cost-effective method of recovering data with minimal effort.

6) Data Sharing

Snowflake's data-sharing feature allows you to share your data with others without creating a new copy of the existing data. No actual data is copied or transferred between accounts; all sharing is done through Snowflake's services layer and metadata store. Therefore, you only have to pay for the computing resources used to query the shared data, as storage is not utilized.

This enables seamless collaboration by allowing multiple Snowflake accounts to access and share data content securely, without duplicating data across the network.

Data Import/Export

Snowflake makes moving data in and out of the platform incredibly easy. It supports a wide range of file formats, including CSV, JSON, Parquet, Avro, ORC, and even XML. Plus, if you're dealing with large datasets stored in cloud storage like Amazon S3 or Google Cloud Storage, Snowflake's external stages allow for continuous data loading without breaking a sweat.

One particularly handy feature is its support for compressed files. This saves storage space and speeds up data transfers—a win-win for anyone working with big data.

7) Data Caching

Snowflake has a caching mechanism that speeds up frequently executed queries, reducing the time it takes to retrieve data from storage. Snowflake first checks if the required data is already cached when a query is executed. If it is, the query can be fulfilled directly from the cache, significantly reducing the time required to fulfill the query.

8) Availability

As Snowflake automatically manages failover and resource allocation, you are unlikely to notice any impact of hardware failures or disruptions. This ensures uninterrupted access to your data, maintaining operational continuity. Network security protocols also help prevent unauthorized access during failover events.

9) Micro-Partitioned Data Storage

In Snowflake, data is stored in encrypted compressed files called micro-partitions. This approach allows Snowflake to scan only the necessary micro-partitions instead of entire tables, which can significantly improve query performance.

10) User-Friendly Interface

Snowflake offers a user-friendly interface, making it easy for users of all levels to work with data. The platform features a web-based interface that enables you to easily manage and manipulate data without needing to write complex code or queries.

11) Snowpark

Snowpark is a collection of intuitive libraries that lets you process non-SQL code within Snowflake. You can write in Java, Python, or Scala—whichever language you prefer—and execute it within Snowflake's virtual warehouses. One of Snowpark's advantages is that it eliminates the need for additional computing, configuration, or maintenance.

12) Automatic Performance Tuning

Snowflake offers a unique and powerful feature that enables automatic query performance optimization. The platform comes equipped with a robust query optimization engine that can automatically fine-tune query settings. This allows you to seamlessly query large datasets without spending time on manual tweaking or configuration.
