NB: An impl note for future reference. Scala allows this.type to support the correct type derivation or compilation error on the function input and output types against derived types. For Java however, the _migration/upgrade_ case of sql.Dataset => sql.Dataset works fine but using more specific derived input types does not as this.type has no meaning. classic.transform(sql.Dataset => classic.Dataset) : classic.Dataset with a lambda _does_ work which allows specific output types if needed later down the line so no functional impact unless derived functions are really needed. -- This is an automated message from the Apache Git Service.
