Configuration Override for ClickHouse Server via Command Line

Official CH changelog text
Configuration settings can be overridden in the command line when you run clickhouse-server. Example: clickhouse-server -- --logger.level=information.
Allows overriding configuration settings directly via command line arguments when running clickhouse-server.

Why it matters

This feature provides a convenient way to change configuration parameters temporarily without modifying configuration files, making it easier to adjust server behavior on startup for debugging or specific runtime needs.

How to use it

Run clickhouse-server with the desired configuration overrides after a double dash. For example, to set the logger level to information, use:

clickhouse-server -- --logger.level=information
