We've been busy at ClickHouse, releasing new software, sharing internals, and hosting events. The latest version, v23.2, includes 18 new features, 30 performance optimizations, and 43 bug fixes. A notable feature is the introduction of multi-stage PREWHERE, which reduces the number of rows a query needs to read. Another significant update is support for Apache Iceberg, a popular data lake format. Additionally, ClickHouse now supports computing correlation matrices and has released a query of the month showcasing its capabilities in real-time analytics. The newsletter also features articles on building ClickHouse Cloud, women who inspire the community, fintech leader Juspay's use case, handling updates and deletes, and upcoming events.
