Research direction
No files, tests, or entry points are named. Start by locating the existing database-link or remote-query architecture in polardbx-sql, then review how MySQL connections, remote DML/DQL/DDL, operator pushdown, system views, and permissions are handled. Done means PolarDB-X can create links to MySQL and PolarDB-X and support the listed remote operations.
