Query high-volume analytics data with an Apache-2.0 columnar database built for real-time OLAP, self-hosting, and SQL reporting.
Store clickstream, product, or usage events and query them with SQL at dashboard speed.
Your workload is small enough for PostgreSQL or your BI tool cache.
Run fast aggregations over logs, metrics, traces, or security events without a fully hosted warehouse.
You need a managed warehouse with no database operations work.
Analytics workloads become expensive when every dashboard, event query, and retention decision runs through a metered warehouse. Teams with high-volume logs, metrics, product events, or user behavior data need fast analytical queries without giving up control over storage and deployment.
ClickHouse stores data by column, which makes aggregation and filtering fast for event, log, and metrics workloads.
The README describes ClickHouse as a database for generating analytical reports in real time, not a general row-store replacement.
Teams can operate ClickHouse themselves or use ClickHouse Cloud when they want the creators to run it.
ClickHouse is better when real-time analytics performance, self-hosting, and cost control over high-volume event data matter. BigQuery and Snowflake are better when the team wants a managed warehouse, broad ecosystem integrations, and less database operations work. ClickHouse rewards teams willing to operate their analytics engine directly.
Self-host ClickHouse with the official Docker image for a local server or evaluation instance.
```bash
docker pull clickhouse/clickhouse-server
docker run -d --name clickhouse-server -p 8123:8123 -p 9000:9000 clickhouse/clickhouse-server
```ClickHouse is best for analytical SQL over large columnar datasets, especially events, logs, metrics, and reporting tables.
No, not for ordinary transactional app workloads. ClickHouse complements PostgreSQL when analytics queries become too heavy for a row-store database.
Yes. ClickHouse reports an Apache-2.0 license in GitHub metadata and can be self-hosted.
