Comparisons

ClickHouse vs BigQuery

BigQuery, limited to GCP, handles ad-hoc queries and complex, long-running analysis effectively, but scaling introduces major challenges in both cost and performance management. A per-query pricing model drives up expenses as usage grows, penalizing expansion.

In contrast, ClickHouse is deployable on any cloud and delivers stable, resource-based pricing with high concurrency and dynamic scaling - ideal for interactive, user-facing workloads without surprise bills.

BigQuery’s query latency

BigQuery often struggles with sub-second queries due to baseline latency on uncached results.

ClickHouse, built for real-time analytics at scale, delivers the fastest and most resource-efficient performance - consistently serving queries in under a second.

Whether you’re aggregating large volumes of data in real-time, interactively slicing and dicing on the fly, or powering customer-facing dashboards, ClickHouse ensures blazing speed.

We needed a solution that could scale, but also provide end-user facing analytics capabilities with low latency and high throughput. Read blog

BigQuery’s high cost

BigQuery’s per-query pricing and streaming insert fees often limit usage, reduce ROI, and penalize frequent ingestion. ClickHouse Cloud avoids these trade-offs with fixed pricing, no per-query or insert costs, and best-in-class resource efficiency - delivering maximum cost-effectiveness at scale.

ClickHouse solves most of our problems very efficiently at a small fraction of the price in terms of infrastructure. This is a far better advantage for us in our books
We simply don’t want the hassle of trying to figure out in advance of how many BigQuery slots to purchase - what a headache! Read blog

BigQuery’s query concurrency

BigQuery caps concurrency based on compute availability, queuing or rejecting queries while charging per query - making high-concurrency workloads costly and unpredictable.

ClickHouse takes the opposite approach: reserve compute once, pay a fixed price, and run 1,000+ queries per node. Need more capacity? Simply add nodes. Costs stay predictable, and scalability comes without slot management or complex tuning.

Another issue was BigQuery's limit of 100 concurrent queries, which created bottlenecks for Gumlet's customers. "If our customers needed to fire more analytics API requests than that, they would fail or go into a queue. Read blog

ClickHouse Cloud gives users precise scaling control with workload quotas, vertical and horizontal scaling (manual or automatic), custom hardware profiles, and fast resume from idle. Users benefit from ClickHouse being open source, making it ideal for hybrid and multi-cloud deployments.

BigQuery, by contrast, shines at elastic scaling for large batch jobs through dynamic slot allocation. But this limits transparency and control: concurrency depends on slot reservations, there’s no vertical tuning or custom hardware choice, and caching mainly aids data skipping. It works well for high-throughput batch workloads, but less so for use cases demanding consistent concurrency and predictable performance.

ClickHouse provides fine-grained scaling control with workload quotas, vertical and horizontal scaling (manual or automatic), custom hardware profiles, and rapid resume from idle. It supports 1,000+ concurrent queries per node with predicate-level cache reuse - ideal for high-concurrency, low-latency analytics.

BigQuery scales elastically for large batch jobs by dynamically allocating slots, but with less transparency and control. Concurrency depends on slot reservations, there’s no vertical tuning or custom hardware choice, and caching mainly aids data skipping. This suits high-throughput batch workloads, but not workloads needing consistent concurrency and predictable performance.

ClickHouse delivers sub-second latency on multi-billion-row datasets with vectorized execution, native aggregates, and dictionary acceleration. Efficient compression reduces I/O, while flexible materialized views and granular cache controls keep hot data instantly accessible for demanding workloads.

BigQuery simplifies infrastructure with a serverless model but depends on reserved slots for concurrency and upfront commitments at scale. It supports large joins and vectorized execution, yet typical latencies are 1–2 seconds. Materialized views have SQL limits, and caching is coarse - skipping broad segments rather than fine predicate-levels - making it better for batch and moderately interactive analytics.

ClickHouse shines at real-time, high-frequency workloads, powering dashboards, product analytics, and customer apps with sub-second responses. Native support for logs, metrics, and traces (via ClickStack) makes it a strong fit for observability Optimizations like projections, dictionaries, and fine-grained caching also make it ideal for GenAI agentic and vector workloads needing fast, high-volume queries.

BigQuery fits internal analytics and operational dashboards, with managed scaling for periodic workloads. But low-latency, high-concurrency use cases, like product analytics, observability, or GenAI agents will struggle with baseline query delays and costly continuous ingestion. Basic caching and SQL-limited materialized views further orient it toward batch scenarios.

With fully-managed CDC via ClickPipes, ClickHouse makes it easy to stream changes from operational databases like Postgres, MySQL or Mongo, enabling real-time analytics with minimal lag. Users benefit from unmatched interoperability, with support for over 70 file formats, external catalogs like Hive and Glue, and open table formats such as Iceberg. External table engines let you query systems like Postgres, MongoDB, or S3 directly.

BigQuery emphasizes interoperability with object stores and open table formats, supporting Avro, CSV, JSON, ORC, Parquet, and Iceberg, with in-place queries via BigLake. Catalog integration is limited to AWS Glue, and CDC relies on Datastream pipelines. This makes BigQuery strong for warehouse and data lake setups, but with less direct multi-system reach.
