Data Warehouses for Marketing Data

The warehouse is where marketing data stops living in tool silos. Three platforms, rated on scale, EU data sovereignty, and low maintenance.

3 integrationseditorially ratedas of June 2026
BigQuery

Google

EU region

Serverless data warehouse for the modern data stack. Petabyte scale, SQL-native, tightly integrated with GA4, dbt, and the Google ecosystem.

4.4

Snowflake

Snowflake

EU region

Cloud data warehouse with elastic separation of compute and storage, a multi-cloud option, and an EU region. The alternative to BigQuery.

4.3

ClickHouse

ClickHouse

EU region

Blazing fast columnar database for real-time analytics. Open-source and easily self-hosted in the EU, but requires data engineering resources as its SQL dialect has quirks.

Scalability
5.0

Serverless into the petabyte range, no cluster management.

5.0

Compute and storage scale elastically and independently.

4.5

Columnar and very fast on large event volumes.

EU data sovereignty
3.5

An EU region exists, but the default is US and the vendor stays Google.

4.0

EU regions on AWS, Azure, or GCP; the vendor itself stays US-based.

4.5

Open source and self-hostable in the EU, data under your control.

Value for money
4.0

Usually cheaper than Snowflake for marketing workloads under 1 TB a month.

3.5

Billed by compute minutes; under 1 TB a month BigQuery is usually cheaper.

4.5

No licence costs, strong performance per euro of infrastructure.

Low maintenance
5.0

No cluster, no updates, no ops team of your own.

4.5

Managed, but warehouses and credits still need governing.

3.0

Needs data engineering resources for operations and tuning.

When it fits
When marketing data from GA4, sGTM and connectors should converge in one queryable place.
When multi-cloud, data sharing or in-house Snowflake skills tip the scales.
When real-time analytics on large event data demands query speed and engineering exists.
When it does not
When a Microsoft or Snowflake stack already exists. Then we build there, not in parallel.
When the setup sits deep in the Google ecosystem; then BigQuery.
When a managed warehouse is enough; BigQuery or Snowflake need less maintenance.

Every value comes from our individual reviews, scored against the review methodology. Prices without warranty, no paid placement.

A data warehouse collects events, campaign costs, and CRM data in one queryable store. Only there do the answers emerge that no single tool can give: real customer journeys, channel contribution margins, clean cohorts.

When this category matters

With the first report that has to join two systems, say GA4 events with ads costs. With the GA4 BigQuery export, which belongs switched on before any migration. And when month-start Excel consolidation eats more time than the analysis itself.

Decision criteria

  • Cost model: usage-based per query (BigQuery), credits (Snowflake), or self-operation (ClickHouse)?
  • EU region available and contractually assurable?
  • Source connectivity: native GA4 export, connector ecosystem, reverse ETL.
  • Low maintenance: who handles scaling, updates, and access?

Asked often

Does marketing need its own warehouse?

As soon as reporting has to join more than one data source, yes. Attribution, cohorts, and customer-level analysis do not work across silo boundaries inside tool UIs.

What does a marketing warehouse realistically cost?

Mid-market BigQuery setups often run below €100 a month, because marketing data volumes are small. It gets expensive through untuned queries and dashboards that recompute everything hourly.
