Why ClickHouse
Real-time analytics over billions of rows
Speed
Column-oriented storage and vectorised query execution return aggregations over billions of rows in under a second.
Efficiency
Per-column codecs deliver high compression ratios, cutting storage cost and keeping far more of your working set in cache.
Scale
Shard and replicate horizontally across nodes, racks and regions, with object storage for cold data.
