ClickHouse Newsletter April 2023: Lightweight Deletes

We've recently updated our website and brand to refresh our look. Our latest version of ClickHouse v23.3 has been released with 22 new features, 14 performance optimizations, and 61 bug fixes. Lightweight Deletes are now generally available, allowing users to efficiently remove specific rows from tables using the DELETE FROM table syntax. This feature is particularly useful for handling updates in non-immutable data and can simplify complex workflows such as incremental materializations. Our newsletter has also been reordered to prioritize the query of the month, which explores the potential impact of Lightweight Deletes on query performance and workflow. Additionally, we've made improvements to our Grafana plugin, and parallel replicas have been introduced to scale query performance by processing data in parallel across multiple ClickHouse hosts. Various upcoming events are available for users to learn more about ClickHouse and its capabilities.
