Low Latency Analytics, Everywhere

ClickHouse excels at business problems that require consistent low-latency response across petabyte tables. It can handle data arrival rates of millions of rows per second. Achievable response times include:

Ad-Hoc queries on source data: 1 second or less
Queries on aggregates: 10 milliseconds or less
Ingestion to query response: 500 milliseconds

ClickHouse dominates in use cases like web analytics, real-time network management, service log analysis, real-time ad bidding, asset valuation in financial markets, and security threat identification.

Who’s Using ClickHouse

Developer Friendly

Thanks to Apache 2.0 licenses for ClickHouse and ecosystem projects, developers can build innovative analytics without spending a cent for proprietary licenses or expensive cloud services. However, there’s a lot more to make a developer happy:

Builds that install in 60 seconds or less
Run ClickHouse and your entire analytic stack in Kubernetes
Robust client connectivity: Python, Javascript, C++, Golang, Java, ODBC
Simple integration with Kafka for rapid data ingestion
A wealth of features designed to solve problems like funnel analysis, last point queries, and pivoting results
Ability to read directly from S3, MySQL, PostgresQL, Redis, and ODBC data sources
Tight integration with popular visualization tools like Grafana, Superset, and Tableau.

Run ClickHouse on Kubernetes

Unrivaled Cost-Efficiency and Flexibility

ClickHouse runs anywhere that Linux does: public clouds, Kubernetes, and on-prem environments. Resource stingy algorithms keep operating costs low while maximizing performance on available hardware. The permissive Apache 2.0 license makes ClickHouse an ideal choice for applications ranging from multi-tenant cloud services to embedded applications.
