OData mapping issue with mongodb --------------------------------- Key: TEIID-5873 URL: https://issues.redhat.com/browse/TEIID-5873 Project: Teiid Issue Type: Enhancement Components: Misc. Connectors, OData Affects Versions: 13.0.1 Reporter: Chee Kin Lim Assignee: Steven Hawkins Priority: Major Fix For: 13.1 Given the following document in MongoDB matrix_variable collection: { "_id" : ObjectId("5b2367c9c9e77c0007ca0111"), "createdOn" : ISODate("2018-06-15T07:16:25.459Z"), "modifiedOn" : ISODate("2018-07-02T02:04:16.661Z"), "variableId" : "183cf101d2334ac09bd0db9aee96081f", "name" : "lfzq_test", "description" : "", "lastModifiedUserEmail" : &quot;admin1(a)abc.com&quot;, "headerRow" : { "rowId" : "0b002942a5b4424f98fcc270af0290c3", "values" : [ "name", "value" ], "isEncrypted" : [ false, true ] }, "rows" : [ { "rowId" : "940467f9bb724d1688086baeec05049b", "values" : [ "lfzq123q", "751c634ca5e24102a00800b386955a5c" ] } ], "deleted" : false } The "headerRow" property is exposed as separate entity type in OData schema, but not "rows" property. I found the following entity types with odata/$metadata: <EntityType Name="headerRow">...</EntityType> <EntityType Name="matrix_variable">...</EntityType> Github repo to showcase the issue: https://github.com/limcheekin/teiid-spring-boot-mongodb-odata Related StackOverflow post: https://stackoverflow.com/a/59385181/303211
