The end-to-end cost-performance of real-time analytics: Snowflake vs. ClickHouse Cloud
Summary
CostBench compares Snowflake and ClickHouse Cloud as end-to-end real-time analytics systems rather than measuring reads on a static, prepared dataset. It evaluates continuous ingest, raw-data organization, pre-aggregation freshness, and continuous query serving while background work continues, testing Snowflake’s standard-table and Interactive Tables paths alongside ClickHouse. The benchmark is designed around fresh data becoming query-ready as it arrives and distinguishes sustained real-time ingest from bulk loading or backfill. In the reported results, ClickHouse achieved 969× better cost-performance than Snowflake’s standard materialized-view setup and 180× better than its Interactive Tables setup; among the tested paths, only ClickHouse incremental materialized views kept pre-aggregations continuously synchronized without lag.
Context
The post argues that static-dataset read benchmarks do not capture the cost or latency of making fresh data query-ready, maintaining derived data, preserving freshness, and serving queries while ingest and maintenance continue. It presents real-time analytics as a full path from continuously arriving data to continuously served answers.
Approach / What changed
CostBench measures continuous ingest, raw-data organization, pre-aggregation maintenance and freshness, and query serving together. The comparison tests ClickHouse against Snowflake’s broadly available standard-table setup and newer Interactive Tables setup, using a workload in which fresh data must become query-ready as it arrives rather than a bulk-load or backfill process.
Takeaways
CostBench measures the running cost and latency of ingest, query-ready data maintenance, derived-data freshness, and query execution together instead of isolating static reads.
The comparison includes Snowflake standard tables and Interactive Tables, while ClickHouse uses query-ready ingest and incremental materialized views for continuously maintained pre-aggregations.
ClickHouse delivered 969× better cost-performance than Snowflake’s standard materialized-view setup and 180× better than Snowflake’s Interactive Tables setup in the expanded benchmark.
