Server Configuration Parameters

This section contains descriptions of server settings that cannot be changed at the session or query level.

These settings are stored in the config.xml file on the ClickHouse server.

Other settings are described in the “Settings” section.

Before studying the settings, read the Configuration files section and note the use of substitutions (the incl and optional attributes).
