ClickHouse
Columnar database for blazing-fast analytics at any scale
Overview
ClickHouse stores data in columns rather than rows, which fundamentally changes the performance characteristics for analytical queries. When you run a query that aggregates a single column across millions of rows, ClickHouse reads only that column - not entire rows - resulting in orders-of-magnitude faster queries than row-based databases.
For product analytics, logging, and time-series data, ClickHouse handles volumes that would bring PostgreSQL to its knees. Billions of events, petabytes of logs, and years of time-series data are queryable in seconds without expensive hardware or complex indexing strategies.
The compression ratios are remarkable. Columnar storage with LZ4 or ZSTD compression routinely achieves 10-20x compression, meaning your storage costs are a fraction of what they would be with traditional databases. More data, less cost, faster queries.
