ClickHouse is the fastest analytical database engine on the market. Developed by Yandex, it processes real-time analytical queries over billions of rows with latencies under 100ms.
Columnar architecture
Unlike traditional row-oriented databases, ClickHouse stores data by columns. This makes analytical queries accessing only a few columns orders of magnitude faster. Columnar compression reduces storage by 5x to 10x.
ClickHouse supports ingestion of up to 1 million rows per second per node. Its MergeTree engine enables time-based partitioning and optimized primary key ordering.
Main use cases
ClickHouse is ideal for real-time dashboards, monitoring, log analysis, recommendation systems, and data warehousing. Companies like Cloudflare, Uber, and eBay use it to process petabytes of data.
ClickHouse as a service
ClickHouse Cloud offers analytical database-as-a-service with auto-scaling and multi-region replicas. Open-source alternatives like Altinity allow on-premise cluster deployment.
For applications needing real-time analytics over large data volumes, ClickHouse is the most powerful option. At Vynta, we design ClickHouse analytical pipelines that transform data into business decisions.
