What is Snowflake?

With the help of its Data Cloud, Snowflake gives every organization the ability to deploy its data. Customers utilize the Data Cloud to combine disparate data sources, discover and safely exchange data, and carry out a variety of analytical activities. Snowflake provides a single data experience that spans various clouds and regions, regardless of where data or users are located. Snowflake Data Cloud is the business engine of choice for thousands of clients across a variety of industries, including 212 of the Fortune 500 for 2021 as of July 31.

A SQL data warehouse built exclusively for the cloud is included in the Snowflake Data Cloud. It combines high performance, high concurrency, simplicity, and affordability to a degree not conceivable with other data warehouses because it was built with a patented unique architecture to manage all aspects of data and analytics.

Despite theoretically integrating storage, computing, and services, Snowflake physically divides these three components (like metadata and user management). Due to the fact that each of these parts is distinct, Snowflake is able to respond quickly and adapt to changing circumstances because each part may be enlarged and contracted individually.

In Snowflake, all compute nodes have access to a single central persisted data repository. However, Snowflake executes queries utilizing MPP (massively parallel processing) compute clusters, which is akin to shared-nothing architecture. In this configuration, a subset of the total data set is stored locally on each node in the cluster.

While keeping costs for cloud data storage at a minimum, Snowflake may also act as your data lake. In a relational format and with complete transactional ACID integrity, a Snowflake data lake can natively ingest and query a wide range of different data types, including JSON, CSV, and tables as well as Parquet, ORC, and more.

Along with elastic infrastructure and integrations for projects in data engineering, data application development, data science, AI, and machine learning, the Snowflake Platform also features a data lake, data sharing, and collaboration tools, and a data marketplace.

Snowflake, a real data platform as a service, automatically manages infrastructure, optimization, infrastructure, data protection, and availability so businesses can concentrate on using data rather than managing it.

Snowflake is a true SaaS product. To be more precise:

  • There is no actual or virtual hardware to choose, set up, configure, or manage.
  • There is hardly any software to set up, manage, or install.
  • Snowflake handles ongoing upkeep, management, upgrades, and tuning.

Snowflake is entirely powered by cloud computing. Except for the optional command line clients, drivers, and connectors, every part of the Snowflake service is run on a public cloud infrastructure.

For its computing requirements, Snowflake uses virtual compute instances, and for durable data storage, it uses a storage service. It is not possible to run Snowflake on private cloud infrastructures (on-premises or hosted).

Snowflake is not a pre-packaged software solution that a user may set up. All facets of software installation and upgrades are handled by Snowflake.

What is Snowflake

The Architecture of Snowflake

The Snowflake database's architecture is a hybrid of the traditional shared disc and shared-nothing database systems. Similar to shared-disk systems, Snowflake persists data in a central location that is accessible from all compute nodes in the platform. Snowflake, on the other hand, executes queries using massively parallel processing (MPP) compute clusters, which are comparable to shared-nothing systems in that each node in the cluster retains a portion of the whole data set locally. This approach combines the shared-disk design's ease of data management with the efficiency and scale-out benefits of a shared-nothing architecture.

The Architecture of Snowflake

Three essential layers make up the distinctive architecture of a snowflake:

  • Database Storage
  • Query Processing
  • Cloud Services

Database Storage

As soon as data is loaded into Snowflake, the program rearranges it into its own efficient, compressed, columnar format. This enhanced data is kept by Snowflake on the cloud. The organization, file size, structure, compression, metadata, statistics, and other aspects of data storage are all managed by Snowflake. It is also in charge of managing other aspects of data storage, such as metadata. Customers cannot directly access or see the data objects that Snowflake stores; Snowflake's data objects can only be accessed through SQL query operations.

Query Processing

The processing layer is where queries are actually executed. "Virtual warehouses" are used by Snowflake to process queries. Each virtual warehouse is an MPP computing cluster with several compute nodes that Snowflake has allotted from a cloud provider. Each virtual warehouse is a separate compute cluster with its own set of resources; they are not shared by other virtual warehouses. Each virtual warehouse, therefore, has no bearing on how well the others perform.

Cloud Services

A group of services called the cloud services layer works together to coordinate operations within Snowflake. Through handling user requests, from login to query dispatch, these services link together all of the various parts of Snowflake. Instances of computing that Snowflake procured from the cloud provider are also used by the cloud services layer.

Cloud layer's services are managed as follows:

  • Authentication
  • Infrastructure management
  • Metadata management
  • Query parsing and optimization
  • Access control

Multiple methods of connecting to the service are supported by Snowflake:

  • A web-based user interface that offers access to Snowflake's whole management and use structure.
  • All facets of utilizing and managing Snowflake can be accessed through command-line clients, such as SnowSQL.
  • Other programs, including Tableau, can connect to Snowflake by using the ODBC and JDBC drivers.
  • Native connectors, such as Python and Spark, that can be used to create programs that connect to Snowflake.
  • Application connectors from third parties that can link Snowflake to ETL systems like Informatica and BI products like ThoughtSpot.

Setting Up A Virtual Warehouse A cluster of computing resources is what Snowflake refers to as a virtual warehouse. To complete tasks in a Snowflake session, this warehouse offers all the necessary resources, including CPU, memory, and temporary storage.

After logging into a Snowflake account, the first thing to do is to construct a virtual warehouse. The first warehouse I made was for ETL, while the second warehouse was for queries.

Execute the following CREATE WAREHOUSE commands in either the SnowSQL CLI or the web-based spreadsheet to create a warehouse:

Databases, Tables, and Views within Snowflake Snowflake maintains databases for all of its data. The logical groupings of database objects, such as tables and views, that make up each database, called schemas, are present in every database. There are no strict restrictions placed by Snowflake on the number of databases, schemas (inside a database), or objects (within a schema) you can make.

Solutions Offered by Snowflake on AWS

The Data Cloud is powered by and accessible through Snowflake's platform, which also offers a solution for data warehousing, data lakes, data engineering, data science, data application development, and data sharing. Data is one of the most valuable assets, a fact that is acknowledged by businesses in every sector. However, the development of data silos is preventing businesses from fully utilizing the promise of data. Extracting value from them costs time and money, and using numerous technologies and clouds makes governance and collaboration practically impossible. The Data Cloud was developed by Snowflake to address this issue. Thousands of businesses from across the world mobilize data on the Data Cloud, which is a global network with nearly limitless scalability, concurrency, and performance.

Some Solutions offered by Snowflake on AWS:

  • Store all of your information: In addition to your relational data, store semi-structured data in formats including JSON, Avro, ORC, Parquet, and XML. Dot notation and conventional SQL that is ACID-compliant can be used to query all of your data.
  • Spend only what you use: Storage scales independently of computing with Snowflake's built-for-the-cloud architecture. You only pay for what you consume, whether it happens gradually over time or transparently and automatically.
  • All users should be supported: Support multiple use cases at once with independent virtual warehouses (computing clusters) that leverage your shared data.
  • Per-second pricing can increase efficiency: So that you are only charged for the time you utilize, turn on and off your compute resources as necessary.
  • Benefit from a full SQL database: Keep investing in the knowledge and resources that you already rely on for your data analytics.
  • In order to give your business units, subsidiaries, and partners secure access to read-only, centralized data, you can more easily create one-to-one, one-to-many, and many-to-many data-sharing partnerships.

Concurrency with Snowflake

Resizing alone won't solve concurrent problems in terms of concurrency testing for a warehouse. For this reason, Snowflake's multi-cluster warehouses are made expressly to handle performance and queuing concerns caused by several concurrent users and/or queries. Once more, multi-cluster warehouses won't be used to create a baseline for the first round of testing. I will set up the warehouse to run in auto-scale mode and setup it up for a multi-cluster operation to alleviate any concurrency issues. This will basically let Snowflake automatically start and stop clusters as necessary.

The Snowflake parallel and concurrency processing options and capabilities, as well as how the virtual warehouse setup influences performance, concurrency, and effectively processing data within the required performance goal time. The other goal of this lecture is to clear up some of the industry misunderstandings about the Snowflake concurrent processing limits. Whenever the topic of concurrency is brought up, we typically think about multi-cluster warehouses. There are two methods for handling concurrency in Snowflake:

  • Parallel or concurrent processing within a single cluster warehouse.
  • Processing in parallel or simultaneously in a multi-cluster warehouse. Additionally, it should be noted that performance and concurrency are essentially two sides of the same coin, and if concurrency is not managed correctly, it can appear to the end user as a performance issue.

AWS Snowflake Unique Advantages

Excellent features and distinctive architecture are included in Snowflake to meet the needs of contemporary businesses. Businesses benefit greatly from its cutting-edge capacity for managing vast amounts of data.

The benefits of utilizing Snowflake that an organization often experiences are listed below.

  1. Simplicity of Use It is possible to swiftly adopt Snowflake as a software as a service (SaaS) without having any negative effects on your regular business operations. There are no pricey software or hardware configurations necessary for its deployment. With Snowflake, analysis is made simpler by consolidating all of your data into one system.

  2. Using the cloud first In order to fully utilize cloud computing technology, the Snowflake data warehouse platform was created. By using cloud-based software and technology, the process of storing and analyzing data is made simpler. Cross-cloud apps and multi-cloud systems are supported by Snowflakes' cloud-oriented design. On leading cloud service providers like Amazon, Microsoft, and Google, this well-known technology can be used.

  3. Performance Compared to other platforms used for data warehouses, Snowflake offers exceptional performance. Due to its sophisticated architecture, customers are able to execute massive amounts of queries and scale up and down according to their needs with ease. Without influencing the performance of the system as a whole, the infinite scalability capability enables users to manage any workload independently.

  4. Economical The pricing structure of Snowflake sets it apart from other suppliers and makes it an affordable data warehouse platform. Customers are liable for the cost of the computer and storage they use. Unlimited data storage is possible with this system at a reasonable cost. Snowflake has a function that lets you turn computers on and off, so you'll only be charged for what you actually use. Snowflake provides a variety of editions to accommodate the usage and price ranges of various types of customers. A minimum utilization of 60 seconds is required before the compute resources are billed on a per-second basis.

  5. Supports Multiple Data Structures Snowflake supports both structured and semi-structured data, in contrast to conventional data warehouse platforms. It enables users to integrate all varieties of structured and unstructured data for analysis and load it into a database without requiring any conversions or transformations. The data storage and querying processes are automatically optimized using Snowflake.

  6. Advanced Data Sharing Capabilities Advanced data-sharing capabilities are supported by snowflake design, which also makes it easier for users to share data with one another. Additionally, it allows for the use of reader accounts to share data with third parties. Directly from the user interface, the reader account can be made.

  7. Self-Management Data sharing, big data workload operations, and warehouse auto-scaling are all supported by the fully managed cloud data warehouse platform known as Snowflake. It makes use of the program called Bridge Data Lake, which enables Snowflake to automatically load data. The Snowflake platform scales up and down without difficulty to meet the needs as they change and can manage numerous tasks independently.

  8. Access & Security One of the key advantages of the platform for the Snowflake data warehouse is its high availability. All of the cloud provider's regions may be used to distribute it. Even when a component or the network fails, it is designed to provide consistent services and has a minimal noticeable impact. By utilizing SOC2 type II and additional standard features, it also provides sophisticated security protections.

The Snowflake architecture was built from the ground up to profit from the cloud, but it also includes certain special features for a solution that is both very appealing and addresses. The ordinary SQL query language is the first tool that Snowflake uses. Since teams won't need to "re-skill," this will be advantageous for firms who already use SQL (which is pretty much everyone).

It's important to note that Snowflake supports the most widely used data formats, including JSON, Avro, Parquet, ORC, and XML. Handling all the disparate data types that exist in a single data warehouse is a typical issue that can be solved by having the capacity to simply store structured, unstructured, and semi-structured data. This is a significant advancement in the use of advanced analytics to provide greater value to the data as a whole.

For utilizing the advantages of native cloud services, Snowflake has a distinctive architecture. Snowflake adopts a more nuanced approach by separating data storage, data processing, and data consumption, whereas the majority of traditional warehouses use a single layer for their storage and computing. The management of storage and compute resources must be done independently because they are fundamentally different. It's wonderful to guarantee extremely affordable storage and more computing for every dollar spent while avoiding a cost increase by combining the two key elements of warehousing.

For both a data engineer and a data analyst, Snowflake offers two different user interfaces for engaging with data. The data engineer or engineers load the data and work from the application side; they are essentially the system administrator and owner.After a data engineer loads the data into the system, data analysts ingest the data and extract business insights from it. Again, Snowflake distinguishes between the two jobs by allowing a data analyst to copy and modify a data warehouse to any degree without changing the original data warehouse.

Last but not least, Snowflake offers fast data warehouse scaling to address concurrency constraints during times of high demand. Without the requirement for data redistribution, which can cause significant inconvenience for end users, Snowflake scales.


  • Solutions like Snowflake offer some clear advantages over conventional platforms, as mentioned above, and data warehousing is quickly migrating to the cloud.
  • The ability to deliver the kind of service, simplicity, and value that businesses in a state of rapid change require and, quite frankly, demand is a major challenge for traditional data warehousing methods and technologies. This is in addition to ensuring that both initial and ongoing costs are controllable and reasonable.
  • Support for the ORC file format and ensuring backward compatibility with the current Tableau workbooks were the two main project limitations that Snowflake unquestionably met.
  • In addition to removing those restrictions, Snowflake also significantly improved performance, provided a user-friendly interface for administrators and users, and allowed the system to expand to previously unattainable levels of concurrency. All of these improvements were made at a manageable cost.
  • As a Cloud Data Warehousing solution, Snowflake is a compelling choice because it was a lot of fun and simple to use.
  • In order to become one of the most popular cloud data platforms, Snowflake has to overcome all the difficulties posed by conventional warehouses. It is the best solution available for data warehousing because of its streamlined user interface, distinctive features, and simplicity of use.
  • Organizations are completely dependent on Snowflake because it owns the deployment infrastructure. Swift action in an emergency is difficult to accomplish. A significant number of clients share the Snowflake shared cloud layer, thus in the event of a security breach, all users will have access to the full database.
