Some use cases: - inner join between two metadata schema would return only data products that belong to both schemas, and one could also filter by fields in either or both schemas - join to the parent data product and then you can filter by the parent's metadata schema fields but return their children Some thoughts: - would be nice if the client doesn't need to know how to do the join but the MetadataSchemaQueryExecutor handles it. Clients could issue a `NATURAL JOIN` in the query like so ```sql select * from my_schema NATURAL JOIN other_schema; ``` - maybe register a virtual parent_data_product table so clients can issue a query joining to the parent data product, again, without having to know the details of how to do the join: ```sql select * from my_schema NATURAL JOIN parent_data_product; ``` -- This is an automated message from the Apache Git Service.
