Learn the key factors you should consider while selecting the right data warehouse for your business.

Cloud Data Warehouses commonly consist of three main parts namely Compute, Storage, and Client (service). The Compute layers consist of multiple Compute Clusters with Nodes that usually process queries in parallel and are grouped virtually to perform computational tasks. The Storage layer is where data is organized in partitions for optimizations and compression while the Client layer is mainly for management purposes.

Having mentioned the three layers of Cloud Data Warehouses, it is important to note that each operator often constructs its architecture differently. The key factors that drive the Snowflake vs Redshift vs BigQuery decision are as follows:

1) Snowflake vs Redshift vs BigQuery: Architecture

  • Snowflake: Snowflake architecture is a hybrid system combing both the characteristics of traditional shared-disk and shared-nothing database architectures. It is natively designed for the Cloud but combines an innovative SQL query engine and it comprises three core layers: Database Storage, Query Processes, and Cloud Service. It has a centralized data repository for a single copy of data that can be accessed by all users from all independent Compute Nodes like a shared-disk architecture but also has Nodes in a Cluster where each Node stores portions of the entire data locally.
  • Amazon Redshift: Amazon Redshift is designed with the shared-nothing Massively Parallel Processing (MPP) architecture. It is made up of Data Warehouse Clusters with Compute Nodes that are split into different units. Each Compute Node has a leader that holds the code assigned to the unit. Client applications such as Standard JDBC and ODBC drivers can communicate with the architectural system of Amazon Redshift and they can be integrated with most existing SQL client applications, Business Intelligence (BI) tools, and Data Mining tools.
  • Google BigQuery: Google BigQuery architecture is a Serverless Cloud offering and its main component is the Dremel on which it is built upon. It possesses the Massively Parallel Processing (MPP) architecture used to query data by reading thousands of rows in a second. Like Amazon Redshift, its nomenclature is the shared-nothing architecture in which data is stored in replicated, distributed units and is being processed in Compute Clusters made up of Nodes. This structure offering by Google BigQuery is flexible whereby different users can transfer their data to a Data Warehouse and start an analysis of the data using standard SQL queries.

2) Snowflake vs Redshift vs BigQuery: Mode of Operation / Performance

  • Snowflake: Snowflake separates its compute power from its storage thereby allowing for concurrent workloads to enable users to run multiple queries at a time. The workload does not affect each other as everything is done separately which results in faster performance.
  • Amazon Redshift: Amazon Redshift delivers fast query speeds on large data sets dealing with sizes up to a petabyte and more, therefore, making it a top choice for running a massive amount of queries but it can be quite slow when using semi-structured data like JSON. Its ability to perform speedy operations sterns from its Columnar Data Storage and Massively Parallel Processing design architecture as they are not separated but carry out operations together. 
  • Google BigQuery: Google BigQuery supports partitioning of storage, and compute as separate operations thereby resulting in improved query performance. Google BigQuery delivers fast and large query speeds on data sets with sizes up to a petabyte and data can easily be queried using standard SQL or through Open Database Connectivity (ODBC).

3) Snowflake vs Redshift vs BigQuery: Setup / Maintenance and Server Management

  • Snowflake: Snowflake does not require the setup of Storage and Compute power as they are separated and would be handled by the Cloud provider but the selection of a Cloud service provider is needed. As for maintenance, a low maintenance level will be required as almost everything is done for you including automatic and rapid provisioning of computing resources. For management, Snowflake is regarded as a more Serverless Management System as every operation occurs on the Cloud provider so there will be close to zero management required from the end-users.
  • Amazon Redshift: Amazon Redshift is regarded as a self-managed system in which some of its operations will require human input and on-premise installation of both hardware and software components. It requires setting up appropriate Clusters as Storage and Compute are not separated, and designing data workflow to match resource size while maintenance in Amazon Redshift requires vacuuming and analyzing tables periodically by the user.
  • Google BigQuery: Google BigQuery can be regarded as a Serverless System as most of its operations are handled by Google on the Google Cloud Platform and no sizing is needed in setup as its Storage and Compute Nodes are separated. As for maintenance, a low level of maintenance is needed from the end-user.

4) Snowflake vs Redshift vs BigQuery: Scalability

  • Snowflake: Snowflake gives room for a seamless, non-destructive scaling that occurs both vertically and horizontally. This is made possible with its Multi-cluster Shared Data Architecture and it does not require the input of a database operator as the scaling is done automatically by Snowflake harnessing all the Cloud tools on offer. For this reason, it is preferred by companies with little resources.
  • Amazon Redshift: Amazon Redshift can be used to scale concurrent files as it supports up to 500 concurrent connections and up to 50 concurrent queries to be run simultaneously in a Cluster. It also does its scaling both vertically and horizontally and does automatically provides different Clusters access to the same data while being used for different purposes.
  • Google BigQuery: Google BigQuery like Snowflake, separates its Compute and Storage Nodes and therefore, users can decide how to scale the processing and memory resources based on their needs. This gives rise to obtaining high scalability of data which is executed in real-time both vertically and horizontally and up to petabytes of data.

5) Snowflake vs Redshift vs BigQuery: Loading of Data

  • Snowflake: Snowflake supports Extract Load Transform (ELT) and Extract Transform Load (ETL) Data Integration methods in which data can be transformed during or after loading into Snowflake. It captures the raw data and then decides the best way to transform it.
  • Amazon Redshift: Amazon Redshift supports both ELT and ETL integrations, as well as standard Data Manipulation Langauge (DML) commands. Amazon Redshift also has a unique way of loading data into it using the COPY command making it possible to work with different Data Streams.
  • Google BigQuery: Google BigQuery also uses the traditional ELT/ETL Batch Data Loading approaches by using standard SQL dialect and it uses Data Streaming to load data row by row using Streaming APIs.

6) Snowflake vs Redshift vs BigQuery: Pricing

  • Snowflake: Snowflake provides on-demand and pre-purchasing pricing plans. Since the usage of Storage and Compute Nodes is different, you can pay for computing on a per-second basis depending on your business and data requirements.
  • Amazon Redshift: Amazon Redshift offers different pricing options such as on-demand pricing where charges can be set per hour, or through its Managed Storage system depending on the instance type, or the number of self-managed Nodes where you can pay for the volume of data monthly.
  • Google BigQuery: Google BigQuery platform offers on-demand and flat-rate subscription models where you are charged for the amount of data returned from each query and for the amount of data storage used.

7) Snowflake vs Redshift vs BigQuery: Ease of Use / Data Type Supported

  • Snowflake: Snowflake is intuitive and simple to use though it requires you to have solid SQL and Data Warehouse knowledge. It supports data types such as JSON, XML, Avro, Parquet, etc.
  • Amazon Redshift: Amazon Redshift requires you to have the background knowledge of PostgreSQL or similar Relational Database Management System (RDBMS) for easy deployment as its query engine is similar to them and it supports JSON data type.
  • Google BigQuery: Google BigQuery is a very user-friendly platform that requires common knowledge of SQL commands, ETL tools and supports JSON, and XML data types.

8) Snowflake vs Redshift vs BigQuery: Backup and Recovery

  • Snowflake: Snowflake uses fail-safe technology instead of backup. Hence, it recovers data that may be lost or damaged due to system failures within a 7-day period.
  • Amazon Redshift: Amazon Redshift uses an advanced system of both automated and manual snapshots of a cluster. The snapshots are stored in Amazon S3 through an encrypted SSL connection.
  • Google BigQuery: Google BigQuery services have data backup and disaster recovery mechanisms that allow users to query point-in-time snapshots from 7 days of data changes.

9) Snowflake vs Redshift vs BigQuery: Security

  • Snowflake: Security on Snowflake is based on your Cloud provider’s features and it provides controlled access management and high-level data security as it is compliant with most Data Protection standards including SOC 1 Type 2, SOC 2 Type 2, PCI DSS, HIPAA, HITRUST, etc.
  • Amazon Redshift: Using Amazon Redshift, security is shared with AWS as security of the Cloud is taken care of by AWS but security in the Cloud is your responsibility so you can set up Sign-in Credentials, Load Data Encryption, SSL Connections, etc. Amazon Redshift is compliant with various security standards such as ISO, PCI, HIPAA BAA, and SOC 1, 2, 3.
  • Google BigQuery: Google BigQuery offers Column-level security that allows for the checking of identity and access status, creating security policies as all data is encrypted and in transit by default. As it is part of the Google Cloud environment, it is compliant with security standards like HIPAA, FedRAMP, PCI DSS, ISO/IEC, SOC 1, 2, 3, etc.

10) Snowflake vs Redshift vs BigQuery: Integrations

  • Snowflake: Snowflake provides native connectivity with various Data Integration, Business Intelligence (BI), and Analytical tools.
  • Amazon Redshift: Amazon Redshift connects with the AWS ecosystem such as Amazon S3, RDS, EMR, etc., along with multiple Data Integration, Business Intelligence (BI), and Analytical tools.
  • Google BigQuery: Google BigQuery integrates with Google Workspace and Google Cloud Platform systems, a wide array of Data Integration, Business Intelligence (BI), and Analytical tools.

11) Snowflake vs Redshift vs BigQuery: Compute Layer

  • Snowflake: Snowflake is a Proprietary Computing Engine with intelligent predicate pushdown and smart caching that runs on commodity virtual machines (AWS, GCP, or Azure) depending on the cloud. C-Store, MonetDB, and other hybrid columnar systems served as inspiration for this Hybrid Columnar System.
  • Amazon Redshift: It is a fork of ParAccel that runs on AWS virtual machines.
  • Google BigQuery: Google BigQuery is a Distributed Computation Engine. This is powered by Borg, a cybernetic life-form that Google has imprisoned inside strategically located data centers throughout the world.

12) Snowflake vs Redshift vs BigQuery: Storage Layer

  • Snowflake: The storage layer in Snowflake is Aa proprietary columnar format that runs in-memory / SSD / object-store on compute/object storage in your chosen cloud. The data is stored in a hybrid columnar format i.e, PAX with aggressive metadata caching.
  • Amazon Redshift: The storage layer in Redshift is Proprietary, but typically SSD (dc1, dc2) / HDD (ds1, ds2) or mixed (for RA3) based on S3 utilizing a proprietary columnar format. RA3 separates computing and storage, whereas all other node types combine compute and storage. RA3 nodes feature a hot query cache as well as a large metadata cache.
  • Google BigQuery: The storage layer in Google BigQUery is proprietary that is stored on the Colossus filesystem and leverages ColumnIO as a storage format. Distributed computing and storage are completely separated.

13) Snowflake vs Redshift vs BigQuery: Compression

  • Snowflake: Snowflake has its own compression layer that is invisible to the user. Unlike BQ, you are not charged for bytes scanned, although this does imply that the query planner can use compression and table statistics to scan less data thus reducing compute cost.
  • Amazon Redshift: Redshift accomplishes transparent compression through the use of open algorithms such as LZO and ZStandard. It has lately launched its own unique compression method (AZ64), although your data type options are currently limited. You have control over which columns are compressed and how they are compressed. It is now able to modify the compression of a column dynamically without requiring an in-place copy.
  • Google BigQuery: It uses proprietary compression that is invisible to the user and is handled by the ColumnIO columnar format. BigQuery continuously compresses data under the hood for you, but your queries are still billed as if you were scanning uncompressed bytes.

14) Snowflake vs Redshift vs BigQuery: Support for Third-Party Tools

  • Snowflake: Snowflake has Snowsight which can perform some basic data visualizations.
  • Amazon Redshift: AWS has its own general access visualization/data modeling software ie, QuickSight, Looker.
  • Google BigQuery: Google GCP has its own general access visualization/data modeling software i.e., Data Studio respectively. In December 2020 GCP acquired Dataform which is a remarkable Javascript-based data modeling solution that can compile queries in real-time.

15) Snowflake vs Redshift vs BigQuery: Caching

  • Snowflake: It has cold data storage separated from hot and warm query caches in intermediate storage. The results of queries are cached for 24 hours (on both local and remote “discs”).
  • Amazon Redshift: It caches queries and results (depending on the node type and available memory/disc capacity).
  • Google BigQuery: It caches queries and offers an adjustable intermediate cache (BI Engine) for Data Studio querying that provides a hot in-memory cache. Cached inquiries are free of charge.

16) Snowflake vs Redshift vs BigQuery: Use Case

  • Snowflake: Snowflake is best suited for companies that are looking for ways to minimize costs by leveraging on the availability of a Cloud Data Warehouse with nearly unlimited, automatic scaling and creditable performance levels.
  • Amazon Redshift: Amazon Redshift is suitable for companies that deal with large-scale data and need quick query responses as Amazon Redshift is built for Big Data Warehousing. It has a flexible pricing model and does not require administrative overhead costs.
  • Google BigQuery: Google BigQuery is best suited for organizations with varying workloads as it allows you to decide how you want to go about querying your data and it is also suited for those interested in Data Mining activities.
