ClickHouse Newsletter March 2023: Contributing to ClickHouse

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.
