Enable the abiltiy to support nested and non-nested message descriptors ----------------------------------------------------------------------- Key: TEIID-4456 URL: https://issues.jboss.org/browse/TEIID-4456 Project: Teiid Issue Type: Enhancement Components: Misc. Connectors Reporter: Van Halbert Assignee: Van Halbert Fix For: 8.12.x, 9.1 Protobuf definition files can have messages defined in a nested and non-nested form. Nested: {code} package bigdata; message DataEntity { .. optional MetaData context = 6; message MetaData { ... } } {code} Non-nested: {code} package bigdata; message DataEntity { .. optional MetaData context = 6; } message MetaData { ... } {code} The ProtobufMetadataProcessor needs to be changed to so that it can create the metadata from either use case. Currently it obtains the child descriptor messages from the parent descriptor.
