- Enables storage of structured, semi-structured and unstructured data
- Offers customer-managed encryption keys for increased data security and control
- Has in-built data visualization and BI tools
- Provides a pay-as-you-go pricing model
However, unlike Snowflake, BigQuery does not offer native support for semi-structured data storage. It focuses primarily on processing structured data at scale.
BigQuery also does not provide the same breadth of governance, compliance, and security certifications like HIPAA, PCI, FedRAMP, etc. that Snowflake's Enterprise edition offers.
But for organizations looking for a fast, serverless data warehouse, BigQuery presents a compelling open source alternative with the power of Google's cloud infrastructure. Its ANSI SQL interface and integration with other Google Cloud services make migration relatively smooth for analytics workloads.
So in summary, while not a direct equivalent, BigQuery offers overlapping capabilities as a cloud data warehouse contender to Snowflake. Its serverless architecture and pricing model create a different value proposition for certain enterprise use cases.
Who is the main competitor of Snowflake?
Snowflake's top competitors in the data warehousing space are:
Amazon Redshift
As one of the leading cloud data warehouse solutions, Amazon Redshift is considered Snowflake's biggest competitor. Redshift offers a fully managed data warehousing service with the ability to efficiently query large datasets across data stored in Amazon S3. It provides scalable compute capacity and integrates natively with other AWS services.
However, Redshift lacks some of Snowflake’s advantages like complete separation of storage and compute, meaning Redshift clusters have fixed storage attached. Snowflake's architecture allows for more flexibility. Also, Snowflake includes numerous optimizations out-of-the-box whereas Redshift requires more hands-on tuning for optimum performance.
Overall, Redshift remains a highly capable cloud data warehouse option with a strong market presence as part of AWS. But Snowflake aims to differentiate through its innovative architecture, focus on automation, and ease-of-use.
