Why developers choose ClickHouse

BigQuery’s query latency

Achieving sub-second query response times and supporting highly concurrent workloads can be painful in BigQuery, if not impossible.
ClickHouse is purpose-built for real-time, large-volume, data analytics. It’s the fastest and most resource-efficient database for analytics and is designed to serve queries with high concurrency without enforcing limits on the number of parallel queries.
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 pricing model can lead companies to artificially constrain usage or access to data, leading to lower ROI.
ClickHouse is designed to manage huge volumes of data efficiently. Its efficient management of resources helps to maximize its cost-effectiveness. ClickHouse was designed from the ground up for best-in-class resource utilization.
For example, Prefect reduced costs by 33% moving from BigQuery to ClickHouse, and Juspay reduced its operating expenses by 10x after migrating its analytics workloads from BigQuery to ClickHouse.
Cost for querying 1 billion rows
Quote
[BigQuery] discourages data usage. Instead of encouraging analysts to query the database in any and all ways they can imagine you’ll end up worrying about needing to limit them and come up with processes for controlling the volume of data being used.
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

When not to migrate from BigQuery to ClickHouse Cloud yet?

If you need multi-statement transactions or extensive joins over highly normalized tables.
Both are on our roadmap for 2025.
