Set up docs MCPThese settings are available in system.settings and are autogenerated from the ClickHouse snapshot.
compatibility
The compatibility setting causes ClickHouse to use the default settings of a previous version of ClickHouse, with exceptions recorded in the settings changes history.
If settings are set to non-default values, then those settings are honored (only settings that have not been modified are affected by the compatibility setting).
Changes marked Ignore in system.settings_changes block rollback of that change and all earlier changes to the same setting.
This setting takes a ClickHouse version number as a string, like 22.3, 22.8. An empty value means that this setting is disabled.
Disabled by default.
compatibility_s3_presigned_url_query_in_path
Compatibility: when enabled, folds pre-signed URL query parameters (e.g. X-Amz-*) into the S3 key (legacy behavior), so ‘?’ acts as a wildcard in the path. When disabled (default), pre-signed URL query parameters are kept in the URL query to avoid interpreting ‘?’ as a wildcard.
