This feature prevents sensitive data from being exposed in error and exception messages, enhancing security and privacy by automatically removing or masking confidential information from logs and user-visible errors.How to use it
Configure thequery_masking_rules section in your ClickHouse server configuration file to define patterns for sensitive data masking. The masking will then also apply to exception messages, removing sensitive content when errors occur.
