Data Warehousing
Winner: It Depends

Snowflake vs Google BigQuery
Snowflake offers superior multi-cloud flexibility and zero-maintenance performance. BigQuery offers effortless serverless scaling and deep integration if you are already on Google Cloud.
The Cloud Data Warehouse Battle
I've lost count of how many Snowflake-vs-BigQuery evaluations I've sat through. They almost always start the same way: someone pulls up a benchmark slide, everyone argues about query speed for fifteen minutes, and then the real decision gets made based on something completely different — usually which cloud the rest of the company is already on.
Let me share what actually tends to drive this decision in the field, because the marketing from both vendors doesn't match the day-to-day reality.
Snowflake's bet was that data teams would want a platform that floats above the cloud providers. It runs on AWS, Azure, and GCP, and the product is nearly identical on all three. The architectural north star is "make SQL teams productive without a platform engineer." Warehouses are T-shirt sized, auto-suspend is built in, and there's a Marketplace for sharing datasets between accounts without copying data. The product is opinionated in a way that makes the first 90 days very pleasant.
BigQuery's bet was that truly serverless would win. There are no clusters to size, no warehouses to resume, no "oh the warehouse was suspended and my first query took 3 seconds" moments. You submit SQL, Google finds capacity from a huge shared slot pool, and you get results. It's the most elegant serverless warehouse I've used — when it clicks, it really clicks.
The real differences
I focus on four things when I'm helping a team decide:
- Your existing cloud footprint. This decides it for 60% of teams. If you're deep in GCP (GA4, BigQuery exports, Vertex AI, Looker) you'd be fighting uphill to pick anything else. If you're on AWS or Azure and don't want a second cloud provider on the invoice, Snowflake is the path of least resistance.
- Pricing predictability. BigQuery on-demand charges by bytes scanned. It's glorious when your queries are well-pruned and cheap, terrifying when someone writes
SELECT * FROM fact_events WHERE date > '2020-01-01'. Snowflake charges by warehouse-second. It's glorious when your workload has clean peaks and auto-suspend catches them, terrifying when someone sets a warehouse to AUTO_SUSPEND = NEVER. - Data sharing requirements. If you share data with external partners, other business units, or customers, Snowflake's Secure Data Sharing is still more mature. BigQuery's Analytics Hub has closed a lot of the gap but is GCP-bound.
- ML and AI integration. BigQuery ML lets analysts train models with SQL — genuinely useful for simple classification and forecasting. Snowflake Cortex added hosted LLMs and vector search in the last couple years and it's catching up fast. For real data science, neither is a substitute for a notebook platform.
Architecture in plain language
- Snowflake: You pick a warehouse size (XS, S, M, L...) and pay per second it's running. Warehouse auto-suspends after N seconds of inactivity and auto-resumes on the next query. Storage is decoupled and you pay for it separately.
- BigQuery: No warehouses at all. Google runs a massive shared pool of "slots" (compute units). Every query dynamically grabs slots. You pay either by bytes scanned (on-demand) or by reserving slot capacity (Editions / Enterprise).
Both decouple storage from compute. Both are columnar. Both support semi-structured data. The architectures look similar on paper but the operating experience is different enough that teams develop strong preferences within a month.

Verdict
This really does come down to workload shape and cloud strategy. Here's how I'd frame it for someone choosing today.
Choose Snowflake if:
- You're on AWS or Azure and don't want a GCP dependency.
- You want multi-cloud optionality — you're on one cloud today but might land on another in the next few years.
- You share data with external partners, customers, or other business units regularly.
- Your workload is predictable enough that picking warehouse sizes feels natural, not stressful.
- Your team includes dbt-first analytics engineers who like having full control over refresh cadences and warehouse assignment.
Choose BigQuery if:- You're already on GCP, or your analytics source of truth is GA4, Firebase, Ads, or another Google product.
- Your workloads are bursty — quiet most of the day with big spikes — and you'd rather not think about sizing.
- Your team prefers pay-per-query over pay-per-time and is disciplined about partitioning and clustering tables.
- You want BigQuery ML to let analysts build models without a notebook stack.
- You're running heavy streaming ingestion — the Storage Write API is excellent.
The hidden gotchas I've seen
- Snowflake: Teams forget to enable auto-suspend, leave big warehouses running over weekends, and get a surprise bill. This is operational hygiene, not a platform flaw, but it's the #1 reason people say Snowflake is "expensive."
- BigQuery: Teams forget to partition fact tables, and one bad
SELECT * with no predicate scans 50 TB. Set project-level maximum-bytes-billed quotas on day one or you'll eventually eat a five-figure query. - Both: Teams significantly underestimate how much the BI semantic layer, dbt choices, and pipeline orchestration matter compared to the warehouse choice. Your warehouse is maybe 30% of the modern data stack experience — the rest is tooling around it.
If I had to pick a default for a new team with no existing cloud allegiance, I'd pick Snowflake today, mostly because the ergonomics are still the best in class and multi-cloud portability is a nice hedge. If the team was already deep in GCP, BigQuery every time.
Frequently Asked Questions
Can I use Snowflake on Google Cloud?
Yes. Snowflake runs natively on AWS, Azure, and GCP in many regions. You can even replicate databases across clouds for DR or data residency. The product is essentially identical on all three — same SQL, same warehouse model, same UI — which is exactly Snowflake's architectural pitch.
Which is cheaper, Snowflake or BigQuery?
Depends on workload shape. For bursty, sporadic workloads BigQuery on-demand is often cheaper because you literally pay zero when idle and pay only for bytes scanned. For steady, predictable BI workloads Snowflake is often cheaper because right-sized warehouses with aggressive auto-suspend beat paying per byte scanned on dashboards hitting the same tables dozens of times a day. The two biggest cost levers are not the platform but (1) partitioning/clustering discipline on BigQuery and (2) warehouse right-sizing plus auto-suspend on Snowflake.
Does BigQuery support data sharing like Snowflake?
BigQuery has Analytics Hub for publishing datasets to other GCP consumers, and it works well — but it's GCP-only. Snowflake Secure Data Sharing works across clouds and regions, and the Marketplace has a much larger catalog of commercial and free data products. If external data sharing is a core use case, Snowflake has a meaningful lead.
Is BigQuery faster than Snowflake?
Not in any consistent way I've measured. Both are fast for well-modeled queries on well-partitioned tables. BigQuery tends to feel faster for one-off ad-hoc queries because there's no warehouse to resume. Snowflake tends to feel faster for BI dashboards because the result cache is aggressive and warehouses stay warm. Unless you have a very specific benchmark that mirrors your workload, treat performance as a tie.
How do Snowflake Marketplace and BigQuery public datasets compare?
Snowflake Marketplace has a broader catalog of commercial data products — financial data, weather, demographics, B2B contact data. BigQuery public datasets are strong for research, government, and Google's own data products. For building a data product to monetize, Snowflake Marketplace is the more serious commercial channel today.
Which platform is better for Python and machine learning?
Both added significant Python support in the last two years but they're still catching up to Databricks. Snowflake Snowpark lets you write Python DataFrames and UDFs that run in-database; BigQuery has stored procedures in Python and BigQuery ML for SQL-based training. For lightweight feature engineering and model inference, either works. For real ML workloads with notebooks, experiment tracking, and GPUs, you'll want a separate ML platform connected to your warehouse.
What about Snowflake Cortex vs. BigQuery Vertex AI integration?
Cortex gives you hosted LLMs, embeddings, and vector search directly in SQL — useful for RAG pipelines and AI features without moving data out of Snowflake. Vertex AI integration in BigQuery is deeper if you're doing custom model training and deployment on GCP. For "I want GPT-style capabilities inside my SQL," Cortex is further along as a turn-key feature. For "I want a full MLOps stack," Vertex wins.
