Thanks @fhueske. I take a closer look at the logic, looks like external catalogs are encapsulated as subschemas of the root schema.
The source tables are checked with subschemas during query validation, but sink tables are not checked accordingly. As per your suggestion, I've fixed `isRegistered()`, `getTable()`, `getRowType()` to check with subschemas, so that the full path of an external sink table are now supported in the `INSERT INTO` clause. Please take a look at the latest commit. [ Full content available at: https://github.com/apache/flink/pull/6508 ] This message was relayed via gitbox.apache.org for [email protected]
