A 50ms query can still be slow and expensive to serve
Before data can be queried, it must be ingested, organized, and kept query-ready.
Sorting, indexing, materialized view maintenance, and freshness all take time and resources.
Traditional benchmarks usually measure only the read step.
CostBench measures the whole path.
Real-time exposes architectural tradeoffs
Most cloud data warehouses were built for batch analytics. Real-time workloads are different: data is constantly arriving and must be immediately available for analysis. CostBench measures how those architectural tradeoffs impact cost and performance from ingestion to insight.

Traditional warehouses
- Designed for batch processing
- Delayed optimization
- Scheduled refreshes
- Additional compute to maintain freshness
ClickHouse
- Query-ready on ingest
- Incremental materialized views: fresh on write
- Continuous optimization
- No separate freshness layer
Read-side cost-performance results
ClickHouse delivers the best query cost-performance of any major cloud warehouse, and the gap widens as data scales.
Lower is better. Relative to ClickHouse (1x).
- Ingest costs up to 82% less
than Snowflake and Databricks. - Preparation costs up to 65% less
than Snowflake and Databricks. - Read costs up to 83% less
than Snowflake and Databricks.
Here's what continuous ingest actually costs
Using a continuous ingest workload of one million rows per second, CostBench measures the cost of keeping data fresh and query-ready at scale.
ClickHouse

Snowflake

This has been tested with the ClickBench dataset.
What systems are truly real-time?
In ClickHouse, data is query-ready as it arrives. Materialized views update incrementally in real time, with no delayed catch-up process required before data becomes usable.
With Snowflake, ordering, indexing, and optimization happen later. Fresh data may be visible quickly, but fully query-ready data can take hours.
Instant. Query-ready as data arrives. No delayed catch-up.
More results coming soon
Same full-path methodology coming for Databricks, BigQuery, and Redshift.
Real-time isn't just fast reads. ClickHouse leads on speed and cost-performance across writes and reads.
Against Snowflake, ClickHouse reaches query-ready data at 22x lower cost, with 28x better write-side cost-performance. On the read side, it leads every warehouse we tested. More write-side comparisons coming next.
Hardware-grounded billing, no opaque credits or DBUs. For agentic workloads that pressure reads and writes continuously, that adds up fast.
