## AI overview

The article reviews benchmark-backed ClickHouse work and argues that practical performance depends on how efficiently a database engine moves data end to end. It highlights JSONBench, which compares ClickHouse with other systems using up to one billion Bluesky events across ingestion quality, storage size, and cold and hot query runtimes. The reported results show ClickHouse achieving substantially faster queries and lower storage usage than traditional JSON data stores such as MongoDB.
