• What technology and infrastructure are you currently using?
• Is your operation at a scale where this choice is significant?

Once you have a clear understanding of these aspects, it's essential to look at the unique tech context of Snowflake and BigQuery. In short, three main factors set these two cloud data warehouses apart: cloud environment, ease of use, and scalability. Let's break these aspects down.

Snowflake is a multi-cloud data warehouse solution that runs on top of Amazon Web Services (AWS), Google Cloud Platform (GCP), and Microsoft Azure. This flexibility allows organizations to choose the cloud provider that best fits their needs or even operate across multiple cloud environments.

BigQuery, on the other hand, is a fully managed, serverless data warehouse developed by Google. It is an integral part of the GCP and leverages Google's Dremel technology to enable fast and scalable analytics.

The distinction between these data warehouses becomes more evident when considering their respective target markets and ease of use. Snowflake is designed to cater to organizations of all sizes, offering flexibility and control over resource allocation with its separation of storage and compute resources. This independence allows for fine-grained management of costs and performance tuning.

BigQuery, in contrast, targets businesses that prefer a hands-off approach to resource management. Its serverless architecture abstracts away the underlying infrastructure, allowing users to focus on their data and analytics without worrying about provisioning or scaling resources.

Another point to ponder is whether your current infrastructure relies heavily on GCP or other cloud providers. BigQuery might have the upper hand if your organization is deeply invested in the GCP ecosystem due to its seamless integration with other Google Cloud services. However, if your organization uses a diverse set of cloud services or is not tied to a specific cloud provider, Snowflake's multi-cloud support and flexibility might be more suitable.

Pricing

• Cost Structure Comparison
  Snowflake uses a separate storage and compute pricing model. This means you pay for the storage you use and the computing resources you consume. Snowflake's compute resources, called "virtual warehouses", are clusters of compute resources that can be scaled up or down depending on the workload, and you only pay for what you use.
  
  BigQuery, on the other hand, primarily charges for data storage and for querying data. However, it has a unique pricing model that's quite different from traditional cloud pricing models. Its serverless approach means you don't pay for compute resources in the same way as you do with Snowflake; instead, you're charged for the amount of data processed by your queries.

Real-World Cost Scenarios

The relative cost of these services can vary significantly depending on the specific use case, data volume, query complexity, and configuration of each platform.

For the most accurate and up-to-date information, you might consider running your benchmarks using a representative subset of your data and queries. This will give you the most relevant comparison for your specific data engineering use case.

Alternatively, you could look for more recent benchmarks published by reputable third-party organizations or consulting firms. Be aware, however, that these benchmarks may not perfectly align with your use case, and they may not take into account all the latest features and improvements of each platform.

Data types

Snowflake supports a wide range of data types, including traditional structured data as well as semi-structured data. Its type system includes numeric types (NUMBER, FLOAT, INTEGER), string types (VARCHAR, CHAR, STRING, TEXT), date and time types (DATE, TIME, TIMESTAMP, with or without time zones), binary types (BINARY, VARBINARY), and semi-structured data types (ARRAY, OBJECT, VARIANT). Snowflake's VARIANT type is particularly flexible, capable of storing any data type, which makes it ideal for handling JSON, XML, Avro, Parquet, and other semi-structured formats.

BigQuery, on the other hand, has a slightly different approach to data types. It supports standard types like INT64, FLOAT64, STRING, and BOOL, along with various date and time types (DATE, DATETIME, TIME, TIMESTAMP). BigQuery also has BYTES for binary data and complex types like ARRAY and STRUCT for handling nested and repeated data. One of BigQuery's unique offerings is the BIGNUMERIC type, which provides higher precision for decimal calculations than its NUMERIC type. Additionally, BigQuery supports a GEOGRAPHY type for spatial data.

A key difference lies in how they handle semi-structured data. While Snowflake uses the flexible VARIANT type, which can store data without a strict schema, BigQuery relies more on its STRUCT and ARRAY types to represent complex, nested structures. BigQuery's approach enforces more schema structure, which can provide stricter data consistency, whereas Snowflake's VARIANT offers more flexibility for dealing with evolving data schemas.
