Building For Fast
summary
ClickHouse demonstrates concrete performance: a public GitHub-events query returns star counts in 14 milliseconds (about 60 such queries per two heartbeats), bulk ingest reaches 1.13 billion rows in 65 seconds (~17 million rows/sec), and a Monte Carlo run evaluates ~100 billion samples in 11 seconds. Engineering delivered a custom consensus service ClickHouseKeeper to replace ZooKeeper, maintains monthly releases, publishes open results via clickbench, and readies a managed service ClickHouse Cloud for early October.
