The latest release of ClickHouse version 25.4 brings numerous exciting features and improvements, including lazy materialization, which defers reading column data until it's actually needed, resulting in significant performance gains; Apache Iceberg time travel, allowing users to run queries based on previous snapshots; correlated subqueries for the `EXISTS` clause, enabling more complex querying capabilities; persistent databases in clickhouse-local, ensuring database persistence even when exiting and relaunching the CLI; default compression codecs for tables and globally for all tables via a config file; and support for the SSH protocol, allowing users to connect directly to the ClickHouse Server. These features are designed to enhance performance, simplify querying, and provide more flexibility in managing data.
