European-only alternative to Snowflake.

Snowflake is the cloud data warehouse that won the analytics market through separation of compute and storage, with EU regions on AWS, Azure or GCP. Snowflake Inc. is a Delaware corporation; the EU regions live on US-hyperscaler infrastructure - meaning two layers of US jurisdiction. For analytics workloads on EU customer data, Schrems II compliance is genuinely difficult on Snowflake. The sovereign alternatives are: ClickHouse (open-source columnar warehouse), DuckDB (embedded analytics), or PostgreSQL with appropriate columnar extensions - all deployable on EU sovereign infrastructure.

Provider: Snowflake
Headquarters: Bozeman, MT
Jurisdiction: United States
Legal regime: CLOUD Act, FISA 702

"EU region" is not sovereignty. Four questions decide it.

Data residency tells you where the bits sit. Sovereignty tells you which legal system can compel access. The answer must hold on all four - or the stack is not sovereign.

Residency

Where is the data physically stored?

Not "in the cloud" - which datacenter, in which country, under which jurisdiction.

Subprocessors

Who else is in your data path?

Every vendor that touches the data: the CDN, the email relay, the error tracker, the analytics pipe.

Jurisdiction

Whose laws can compel disclosure?

A US-headquartered provider falls under FISA 702 and the CLOUD Act - even when the bits sit in Frankfurt.

Key custody

Who actually holds the encryption keys?

If the cloud provider holds both the data and the keys, the data is readable by them - regardless of any DPA.

Fails AWS · Azure · GCP · EU region

Fails on jurisdiction and key custody.

EU bits, US-headquartered parent, US subprocessors in the default path, provider-managed keys.

Passes Binadit managed stack

Passes on all four.

EU-hosted on EU-headquartered infrastructure. Zero US subprocessors in the default path. Customer-held or EU-KMS keys. Listed by name in your Article 28 DPA.

Why teams are exiting Snowflake

Snowflake exits we have scoped come from regulated workloads where the analytics warehouse holds personal data of EU customers, and the Schrems II analysis fails on multiple layers. The unique migration challenge: data warehouses are large, queries are complex, and dbt / Looker / Tableau pipelines need re-pointing. The honest answer for a Snowflake exit is 3-6 months of careful work, not a quick swap. Where the savings are: Snowflake credits at scale ($20k-100k+/month is common) compress to ClickHouse on EU bare metal at a fraction.

Snowflake services and their EU-only equivalents

A migration is not "swap one box for another". The mapping below is what we run for clients leaving Snowflake on Schrems II grounds - full EU jurisdiction, no US parent in the data path.

Snowflake service	What we run instead	Engineering note
Snowflake compute (warehouses)	Binadit Managed Cloud Platform. ClickHouse or PostgreSQL with columnar extensions, modelled with dbt.	ClickHouse is the strongest sovereign alternative for OLAP workloads. For ad-hoc query workloads, Trino over EU object storage is the lakehouse pattern.
Snowflake storage	Binadit Managed Cloud Platform. Tiered MinIO or Ceph pools, with lifecycle rules moving cold data to cheaper disk.	For lakehouse architecture, EU S3-compatible storage as the data layer with ClickHouse or Trino as the query engine.
Snowpipe (continuous ingestion)	Binadit Managed Cloud Platform. Kafka or Redpanda into ClickHouse, orchestrated with dbt.	For Kafka-based ingestion, ClickHouse has native Kafka engine. For batch ingestion, Airflow on EU compute.
Streams & Tasks	Binadit Managed Cloud Platform. PostgreSQL triggers and LISTEN/NOTIFY, or Kubernetes CronJobs for scheduled work.	Materialized views in ClickHouse cover most "Stream" use cases.
Snowpark (Python/Scala in DB)	Binadit Managed Cloud Platform. PostgreSQL with PL/Python, or workers next to the database in Python.	For ML and feature engineering at the warehouse layer, PySpark on EU compute is the standard pattern.
Time Travel + Zero-Copy Cloning	Binadit Managed Cloud Platform. pgBackRest point-in-time recovery, with ZFS or Ceph snapshots for instant clones.	Snowflake's Time Travel is a unique feature; ClickHouse snapshots provide a rougher equivalent.
Secure Data Sharing	Binadit Managed Cloud Platform. Read-only replicas, signed exports, or a scoped API in front of the dataset.	Secure Data Sharing has no direct equivalent; the migration involves redesigning the data-sharing pattern.
Snowflake Marketplace	Binadit DevOps & Support. The components you actually use, deployed and operated as part of your stack.	For datasets you currently subscribe to via Marketplace, direct vendor contracts are typically required.
Snowflake Cortex (LLMs)	Binadit Private Infrastructure. Self-hosted open-weight models on dedicated GPU hardware, served through vLLM or Ollama.	Cortex is recent; the sovereign EU LLM space (Mistral, Aleph Alpha) has matured to be a real alternative.
BI tool integrations (Tableau, Looker, dbt Cloud)	Binadit Managed Cloud Platform. Apache Superset or Metabase, connected to your warehouse.	The BI tool layer typically transfers cleanly with new connection strings; dbt Cloud → dbt Core on self-hosted EU CI.

How we migrate off Snowflake

A typical mid-market migration runs in three phases. The numbers below assume a 6-10 person engineering team and a moderately complex application stack.

Weeks 1-3

Architecture decision + audit

Decide ClickHouse vs Trino+lakehouse vs PostgreSQL based on query patterns and data volume. Inventory every dbt model, every dashboard, every external integration. The architecture decision dominates the schedule.
Weeks 3-10

Pilot + parallel run

Migrate a representative subset of workloads to the EU target. Run parallel for validation. Tune ClickHouse cluster sizing based on real query patterns. dbt models converted (most run unchanged on dbt Core with adapter swap).
Weeks 10-24

Full cutover

Phased migration of remaining workloads. BI tools repointed. Snowflake accounts scoped down. Final cutover with a rollback plan; Snowflake retained for archival access for 60-90 days post-cutover.

5-year TCO on Snowflake → ClickHouse migrations: typically 60-85% cheaper at scale. A team running $50k/month of Snowflake credits often replaces it with €5-10k/month of EU ClickHouse infrastructure plus the managed-partner fee. The break-even point is around $5-10k/month of Snowflake spend; below that, the engineering cost of migration may exceed the saved spend over a 3-year horizon.

Frequently asked questions

View all frequently asked questions

Snowflake has Frankfurt and other EU regions - does that solve GDPR?

No. Snowflake Inc. is US-headquartered (parent jurisdiction), and the EU regions run on AWS/Azure/GCP - also US-headquartered (infrastructure jurisdiction). Two layers of US legal exposure under the CLOUD Act and FISA 702. For Schrems II-strict workloads, neither is acceptable.

Is ClickHouse really comparable to Snowflake?

For OLAP query workloads, ClickHouse is genuinely competitive - often faster on equivalent hardware. The differences: ClickHouse requires more operational expertise, Snowflake's separation of compute and storage is harder to replicate cleanly, and Snowflake's ecosystem (Marketplace, Cortex, etc.) doesn't fully exist on ClickHouse. For pure analytics workloads, the gap is small.

What about managed ClickHouse offerings with an EU region?

Check what the EU region actually runs on. Several managed analytics platforms advertise an EU region that is itself hosted on a US hyperscaler, which leaves you with exactly the dual jurisdiction problem you were trying to solve, one layer further down. We run ClickHouse on infrastructure where that question has a single answer.

How does dbt fit in?

dbt Core is open-source and runs anywhere; dbt Cloud is dbt Labs Inc. (US). For sovereign workloads, dbt Core on a self-hosted CI runner (GitLab CI EU, Forgejo Actions) replaces dbt Cloud. The actual dbt models port cleanly with the warehouse adapter swap (snowflake → clickhouse).

How long does a Snowflake exit really take?

For a small-to-mid Snowflake usage ($5-20k/month, dozens of dbt models): 3-6 months elapsed time. For enterprise Snowflake ($50k+/month, hundreds of models, complex data sharing): 9-18 months. Snowflake migrations are not weekend projects - they require planning, parallel runs, and careful BI-layer choreography.

Can we keep some Snowflake and migrate the rest?

Hybrid is sometimes the right answer for very specific Snowflake-only features. The discipline: keep only non-personal-data workloads on Snowflake (e.g. internal analytics on aggregated metrics with no PII), and document the boundary in the DPA. For most regulated workloads, full exit is cleaner than the documentation burden of a hybrid.
