I do similar work in another issue [FLINK-15191|https://issues.apache.org/jira/browse/FLINK-15191], maybe we can work together.

> In order to support DDL computed column for a connector, we should
> * Add supported key as "schema.#.expr"
> * Fix the TableSource#getReturnType and TableSource#getProducedDataType if it use the virtual columns as part of its schema
> * Fix the format schema if the schema is derived from the TableSchema and the TableSchema contains virtual columns.
