How ClickHouse® Inspired Us to Build a High Performance Time Series Database
summary
Explains how VictoriaMetrics copies ClickHouse ideas into a real TSDB: Prometheus-compatible ingestion with high-frequency inserts, a custom on-disk layout that stores samples per series and an inverted index per label to find series fast, compression and a gorilla-like value codec to cut disk by multiple×, single-binary deployment plus proxy for replication and sharding, and production numbers (millions of series, sustained writes) showing the design scales and reduces CPU and I/O.
