Overview
Documentation-only updates to the Java JDBC integration guide (
jdbc.mdx).Adds a Readonly Profiles note under connection configuration: the driver intentionally omits default connection settings to stay compatible with read-only profiles, and recommends
readonly=2when users need format-related server settings (e.g. reading JSON as a string), with a link to the constraints-on-settings docs.Adds a JSON Type section under special types: default
Map<String, Object>mapping with a nested example, optional string reads via connection/server settings (jdbc_read_json_as_string/OUTPUT_FORMAT_BINARY_WRITE_JSON_AS_STRING), and guidance on JSON number quoting for ClickHouse 25.8+ vs older servers viaoutput_format_json_quote_*server settings.Reviewed by Cursor Bugbot for commit 6f629dd.
