ClickHouse vs Snowflake vs BigQuery for Analytics
Analytical database choice in 2026 is one of the most consequential platform decisions. Honest tradeoffs.
ClickHouse: open-source columnar
ClickHouse is open-source, columnar, and extremely fast at scans. You operate the cluster (or pay for ClickHouse Cloud); the choice trades operational cost against query cost.
- Open-source columnar. Vectorised execution engine; extremely fast scans on analytical workloads; the speed is the product.
- Self-host or Cloud. Self-host gets the lowest unit cost; ClickHouse Cloud removes the operational tax at managed pricing.
- Sweet spot. High-volume analytical workloads where query latency matters; product analytics, observability, log search.
- Trade. Operational complexity; sharding, replication, ZooKeeper/Keeper coordination; team needs the muscle.
Snowflake: managed warehouse
Snowflake is the managed warehouse with the broadest ecosystem. Separation of storage and compute, multi-cloud, mature governance; the trade is per-credit cost.
- Managed. Zero operational overhead; the team focuses on schema and queries, not on the cluster.
- Storage / compute split. Independent scaling; cheap storage, on-demand compute; pay only for what you query.
- Multi-cloud. Runs on AWS, GCP, Azure; reduces vendor lock-in at the cloud layer.
- Trade. Per-credit cost adds up at scale; without auto-suspend and right-sized warehouses, the bill compounds.
BigQuery: serverless analytics
BigQuery is the serverless option: no cluster, no warehouse to size, pay-per-scan or flat-rate slots. Tightly integrated with GCP; the right choice when you live in GCP and want analytics without provisioning.
- Serverless. No cluster to size or maintain; submit query, get result; the operational story is "submit and wait."
- Pay-per-scan. Charged on bytes scanned; partition pruning and column pruning are the cost levers.
- GCP-native. Tightly integrated with Cloud Storage, Pub/Sub, Dataflow; the GCP analytics centre of gravity.
- Trade. Pay-per-scan can explode under uncapped queries; one bad analyst, one big bill; flat-rate slots cap the risk.
Cost at common volumes
For 1 PB stored, 10 TB scanned per day, the rough monthly costs land roughly here. Numbers are 2026 list prices; negotiated commitments cut them substantially.
- ClickHouse Cloud. $5-15k/mo at this volume; the lowest managed unit cost for analytical workloads.
- Snowflake. $20-60k/mo with reasonable warehouse sizing; auto-suspend is mandatory at this volume.
- BigQuery. $40-150k/mo on-demand; $20-50k/mo with flat-rate slots; cap the on-demand path or budget cap it.
- ClickHouse self-hosted. Cheaper than ClickHouse Cloud; budget for 1-2 engineers operating the cluster as the offset.
Antipatterns
- BigQuery on-demand on uncapped queries. Bill explodes; one bad analyst.
- Snowflake without auto-suspend. Idle warehouse keeps charging.
- ClickHouse without operational discipline. Unhealthy cluster > saved subscription.
What to do this week
Three moves. (1) Run a 30-day trial of the candidate against your real workload. (2) Compare TCO + workflow fit, not just feature checklists. (3) Decide and commit; running both in parallel is the most expensive option.
